Final position: adjustable to +/– 3°
Limit switch and solenoid
valve mounting: VDI / VDE 3845
Control pressure: max. 10 bar (EB 4 max. 8 bar)
Control air: clean and dry air
at circuits 2/min please lubricate
Temperature range: – 20/+85 °C
As special version: – 40/+120 °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 characteristic by multiple piston guide.
- Operational safety and longservice life caused by the exact machi-
ning of actuator cylinder.
The double acting version of this series is available in 9 sizes, con-
structed to the scotch-yoke principle.
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 - close
Currentless - 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
- Chemical industry

The torques shown in the diagramm are measured values. The requi-
red size of the actuator can be established by comparing the values
of the actuator with the required torque of the valve.
Effective torque in Nm
Especially non-lubricant media (e.g. bulk goods and dry gases) may
cause an increasement of the actuators torque. This is why we recom-
mend to consider a safety of 12%. Choosing an actuator in critical
limits, please contact our engineers. We offer our service with the
Know-How of 30 years of process engineering to you.
