TRANSCRIPT
PNEUMATIC ACTUATOR EB-DW, DOUBLE ACTING
TECHNICAL DATATorque: 27–4001 Nm (control air pressure 6 bar)
Final position: adjustable to +/– 3°
Limit switch and solenoidvalve 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
Valve interface: EN ISO 5211
Actuator cylinder: Aluminium, hard anodized.Other coatings upon request.
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
- Chemical industry
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.
4.1EB-DW
The double acting version of this series is available in 9 sizes, con-structed to the scotch-yoke principle.

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 consider a safety of 12%. Choosing an actuator in critical limits, please contact our engineers. We offer our service with theKnow-How of 30 years of process engineering to you.

Control air pressure
When the left positioned control connection is pressurised, the pistonsare pushed together with the yoke turning counter-clockwise to openthe valve. When the right positioned control connection is pressurised,the yoke turns clockwise to close the valve.
The stroke of the piston can be limited by the adjustment of the screws located in the end covers.
