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

Air moment opening

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.
