PNEUMATIC ACTUATOR EB-EW, SINGLE-ACTING
TECHNICAL DATATorque: 35–1368 Nm (control air pressure 6 bar)
Final position: adjustable to +/– 3°
Limit switch and solenoidvalve mounting: VDI / VDE 3845
Control pressure: min. 3 bar, max. 10 bar
Control air: clean and dry air at circuits � 2/min please lubricate
Temperature range: – 20/+85 °C
Valve interface: EN ISO 5211
Actuator cylinder: Aluminium, hard anodized.Other coatings upon request.
THE ADVANTAGES- High opening- and closing-torques caused by scotch-yoke
construction principle
- Very good sliding charakteristic by multiple piston guide.
- Operational safety and longservice life caused by the exact machi-ning of actuator cylinder.
FEATURES- Maintenance-free, continious lubrication
- Suitability for valves with an angle of 90°
- Blow-proof shaft bearing
- Torques in agreement with EN ISO 5211
- Control pressure min. 2 bar, max. 10 bar
- Good visible elastic position indicator
- Function return by turning the supply plate:Currentless - closeCurrentless - open
- All elements of connection are made of stainless steel.
Possibilities of mounting and accesories are shown in chapter 4.3.
GENERAL APPLICATIONS- Water and wastewater technology
- Shipbuilding
- Swimming pool technology
- Bulk handling
- Pneumatic conveying systems

Typical torque curve of a scotch-yoke actuator.
The torques shown in the diagramm are measured values. The requi-red size of the actuator can be established by comparing the valuesof the actuator with the required torque of the valve.
Especially non-lubricant media (e.g. bulk goods and dry gases) maycause an increasement of the actuators torque. This is why we recom-mend to cosider a safety of 12%. Choosing an actuator in critical li-mits, please contact our engineers. We offer our service with theKnow-How of 20 years of process engineering to you.
