FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1
bull The solenoid valves satisfy all relevant EU directivesGENERAL Differential pressure 2 - 10 bar [1 bar = 100 kPa]Flow (Qv at 6 bar) 700 lmin (ANR)Pilot mounting interface surface ISO 15218 (CNOMO E0636120N size 15)

Direct or Pilot Operated Solenoid Valves (32-52-53) - 17
FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV (551 series) and EXIDA (551-553 series) certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1
bull The solenoid valves satisfy all relevant EU directives

Direct or Pilot Operated Solenoid Valves (32-52-53) - 17
FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV (551 series) and EXIDA (551-553 series) certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1
bull The solenoid valves satisfy all relevant EU directives

Direct or Pilot Operated Solenoid Valves (52-53) - 9
FEATURESbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV (551 series) and EXIDA (551-553 series) certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1

Direct or Pilot Operated Solenoid Valves (32-52-53) - 17
FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV (551 series) and EXIDA (551-553 series) certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1
bull The solenoid valves satisfy all relevant EU directives

FEATURES High quality coil resistance to heat amp moisture and suitable for high ambient
temperature amp harsh environment The same spool valve can be adapted for 32 or 52 functions for controlling
double-acting and single-acting actuators All the exhaust ports of this spool valve are pipe-able providing better
environmental protection particularly recommended for sensitive areas such as applications in the pharmaceutical and food industries
Non Breathing construction where the spring return chambers of the single or double acting actuator are collected with the solenoid valve exhaust
NAMUR design (LH Orientation amp RH Orientation) ensures supply and exhaust ports of the solenoid valve are facing down to prevent water and ingress
Robust and long lasting 316L Stainless Steel Manual Operator (maintained manual operator)
The solenoid valves satisfy all relevant EU Directives For NAMUR type 52 can be converted to 32 NC by rotating NAMUR plate

FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1

FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1
bull The solenoid valves satisfy all relevant EU directivesGENERAL Differential pressure 2 - 10 bar [1 bar = 100 kPa]Flow (Qv at 6 bar) 700 lmin (ANR)Pilot mounting interface surface ISO 15218 (CNOMO E0636120N size 15)

FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1

FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1
bull The solenoid valves satisfy all relevant EU directivesGENERAL Differential pressure 2 - 10 bar [1 bar = 100 kPa]Flow (Qv at 6 bar) 700 lmin (ANR)Pilot mounting interface surface ISO 15218 (CNOMO E0636120N size 15)

Direct or Pilot Operated Solenoid Valves (32-52-53) - 17
FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV (551 series) and EXIDA (551-553 series) certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1
bull The solenoid valves satisfy all relevant EU directives

Direct or Pilot Operated Solenoid Valves (32-52) - 23
Prefix SC
Prefix WP
FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1
bull The solenoid valves satisfy all relevant EU directivesGENERAL Differential pressure 2 - 10 bar [1 bar = 100 kPa]Flow (Qv at 6 bar) 700 lmin (ANR)Pilot mounting interface surface ISO 15218 (CNOMO E0636120N size 15)

FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1

Direct or Pilot Operated Solenoid Valves (32-52) - 19
FEATURES High quality coil resistance to heat amp moisture and suitable for high ambient
temperature amp harsh environment The same spool valve can be adapted for 32 or 52 functions for controlling
double-acting and single-acting actuators All the exhaust ports of this spool valve are pipe-able providing better
environmental protection particularly recommended for sensitive areas such as applications in the pharmaceutical and food industries
Non Breathing construction where the spring return chambers of the single or double acting actuator are collected with the solenoid valve exhaust
NAMUR design (LH Orientation amp RH Orientation) ensures supply and exhaust ports of the solenoid valve are facing down to prevent water and ingress
Robust and long lasting 316L Stainless Steel Manual Operator (maintained manual operator)
The solenoid valves satisfy all relevant EU Directives For NAMUR type 52 can be converted to 32 NC by rotating NAMUR plate

Direct or Pilot Operated Solenoid Valves (32-52) - 19
FEATURES High quality coil resistance to heat amp moisture and suitable for high ambient
temperature amp harsh environment The same spool valve can be adapted for 32 or 52 functions for controlling
double-acting and single-acting actuators All the exhaust ports of this spool valve are pipe-able providing better
environmental protection particularly recommended for sensitive areas such as applications in the pharmaceutical and food industries

FEATURES High quality coil resistance to heat amp moisture and suitable for high ambient
temperature amp harsh environment The same spool valve can be adapted for 32 or 52 functions for controlling
double-acting and single-acting actuators All the exhaust ports of this spool valve are pipe-able providing better
environmental protection particularly recommended for sensitive areas such as applications in the pharmaceutical and food industries
Non Breathing construction where the spring return chambers of the single or double acting actuator are collected with the solenoid valve exhaust
NAMUR design (LH Orientation amp RH Orientation) ensures supply and exhaust ports of the solenoid valve are facing down to prevent water and ingress
Robust and long lasting 316L Stainless Steel Manual Operator (maintained manual operator)
The solenoid valves satisfy all relevant EU Directives For NAMUR type 52 can be converted to 32 NC by rotating NAMUR plate

Direct or Pilot Operated Solenoid Valves (32-52) - 19
FEATURES High quality coil resistance to heat amp moisture and suitable for high ambient
temperature amp harsh environment The same spool valve can be adapted for 32 or 52 functions for controlling
double-acting and single-acting actuators All the exhaust ports of this spool valve are pipe-able providing better
environmental protection particularly recommended for sensitive areas such as applications in the pharmaceutical and food industries
Non Breathing construction where the spring return chambers of the single or double acting actuator are collected with the solenoid valve exhaust
NAMUR design (LH Orientation amp RH Orientation) ensures supply and exhaust ports of the solenoid valve are facing down to prevent water and ingress
Robust and long lasting 316L Stainless Steel Manual Operator (maintained manual operator)
The solenoid valves satisfy all relevant EU Directives For NAMUR type 52 can be converted to 32 NC by rotating NAMUR plate

Direct or Pilot Operated Solenoid Valves (32-52) - 23
Prefix SC
Prefix WP
FEATURESbull The solenoid operated spool valves have threaded port connections and NAMUR
interfacebull The same spool valve can be adapted for 32 NC or 52 functions for controlling
double-acting and single-acting actuatorsbull All the exhaust ports of the spool valve are connectable providing better environmental
protection Particularly recommended for sensitive areas such as clean rooms and applications in the pharmaceutical and food processing sectors
bull The valves offer environmental protection against the ingress of liquids dusts or other foreign matter (environmentally-protected construction)
bull Can be externally piloted (external air pilot supply) to convert valve to zero minimum operation by flipping a gasket
bull The monostable spool valves in conformity with IEC 61508 Standard (2010 route 2H version) have TUumlV certified with integrity levels SIL 2 for HFT = 0 SIL 3 for HFT = 1
bull The solenoid valves satisfy all relevant EU directivesGENERAL Differential pressure 2 - 10 bar [1 bar = 100 kPa]Flow (Qv at 6 bar) 700 lmin (ANR)Pilot mounting interface surface ISO 15218 (CNOMO E0636120N size 15)
