HERMETIC VALVES
– 6060, with right charging
connection;
– 6070, with left charging
connection.
The charging connection is shut
off by the back-seating of thespindle.
The materials used for the main
parts are:
• ST-UNI EN 12165 - CW 617N
hot-forged brass for the main
body;
• especially treated steel for
the spindle;
• aramidic and chloroprene
gaskets for the gland seal;
• glass reinforced PBT for the
cap.
MATERIALS
6020
6010/2
Hermetic valves are used in
systems operating with
hermetic compressors.
They can be used withrefrigerant fluids CFC, HCFC
and HFC.
These valves are available in
the following types:
• shut-off valves with
2 connections: 6010/2 and
6012/22;
• valves with 3 connections
(2 connections + 1
charging/manometer
connection): 6020;
• monobloc valves with
3 connections (2 connections
+ 1 charging/manometer
connection):

STOP VALVES
6165, 6175 and 6170 stop
valves are specially designed
for application on split air
conditioners.They can be used with
refrigerant fluids CFC, HCFC
and HFC.
The very compact design of
these brass valves allows
minimum dimensional sizes and
the fixing flange complies with
current market requirements.
Valves 6170 and 6175 must be
completed with valve core
8394/A or 8394/B and cap and
gasket type 8392/A, to be
ordered separately.
The materials used for the main
parts are:
• ST-UNI EN 12165 - CW 617N
hot-forged brass for thebody;
• TN-UNI EN 12164 - CW 614N
brass for spindle and cap;
• chloroprene rubber (CR) for
outer seal gaskets.
Only for the 6170 group of
valves, aramidic and
chloroprene gaskets for the
gland seals.

Castel diaphragm valves are
particularly suitable for use on
refrigerating systems operating
with refrigerant fluids CFC,HCFC and HFC.
Diaphragm valves don’t have
gland seal. External sealing is
ensured by thin metal discs
(diaphragms) ensuring hermetic
sealing of the area through
which the fluid flows.
The materials used for the main
parts are:
• ST-UNI EN 12165 - CW 617N
hot-forged brass for the body
and the cap;
• nylon for the seat sealing
gasket;
• harmonic steel for the spring.

ROTALOCK VALVES
Castel Rotalock valves can be
used for refrigerating systems
operating with refrigerant fluids
CFC, HCFC and HFC.
Rotalock valves can be
mounted with 7910 and 7990
gaskets, and ensure fast
installation and safe sealing.
Tightness is assured by the
torque of the ring on the
coupling. Before tightening it is
possible to turn the valve in
every direction. All Rotalock
valves have an additional male
connection which can be
excluded by the back sealing of

GLOBE VALVES
Globe valves can be used on
refrigerating systems in order to
intercept the refrigerant fluids
CFC, HCFC and HFC.
Globe valves are manufactured
in two basic types: 6510 with
straight connections and 6530
with angle connections.
Valves 6520, which have
straight connections, are
supplied with flanges. In this
application, copper pipe is
soldered on a brass bush and
not directly on the valve.
Globe valves have large orifices
to keep the pressure drop to a
minimum. On the top of the
caps there is a square seat,
fitting it on the spindle it is
possible to use the cap as an
operating wrench.
The materials used for the main
parts are:
• ST-UNI EN 12165 - CW 617N
hot-forged brass for body,
plug and cap;
• especially treated steel for
spindle;
• aramidic and chloroprene
gaskets for gland seal;
• chloroprene rubber (CR) for
outer seal gaskets;
• P.T.F.E. for seat gasket.

BALL VALVES
6590 ball valves have been
exclusively designed andmanufactured for refrigerating
systems operating with
refrigerant fluids CFC, HCFC
and HFC.
The valve design ensures the
internal equilibrium of pressures
when the valve is closed,
permits the bi-directional flow
of the refrigerant and,
consequently, the assembly on
the plant without taking into
account the direction of the
refrigerant.
The assembling of the spindle
CONSTRUCTION
APPLICATIONS
6590/M42
from the inside prevents any
risk of explosion.
The opening and closing of the
valve is realised by turning thespindle one fourth of a turn.
A standstill in turning realises
either a full opening or a full
closing, moreover the arrow
printed on the spindle head
shows the flow direction.
Electric welding of the bodies
and “O ring“ assembled on the
spindle prevent leaks.
The materials used for the main
parts are:
• ST-UNI EN 12165 - CW 617N
hot-forged brass for body;• ST-UNI EN 12165 - CW 617N
chromium plated brass ball;
• especially treated steel for
the spindle;
• P.T.F.E. for ball gaskets;
• chloroprene rubber (CR) for
outer seal gaskets;
• solder copper connections;
• glass reinforced PBT for cap.

These valves are normally
mounted on the body of the
refrigerating compressor, on
both suction and dischargesides. They can be used with
refrigerant fluids CFC, HCFC
and HFC.
Compressor valves have a
threaded connection that can
be used both as charging or
gauge connection. The
charging connection is cut off
by the back-seating of the
spindle. The compressor valves
are oval flanged with SAE-
FLARE connection to fit copper
pipes through a suitable nut.
The materials used in the
construction of the main parts
are:
• ST-UNI EN 12165 - CW 617Nhot-forged brass for the
body, flange and bush;
• especially treated steel for
the spindle;
• aramidic and chloroprene
gaskets for the gland seal;
• steel for the cap;
• glass reinforced PBT for the
cap.
