Hydraulic actuators

Our new hydraulic rotary actuators for 90°-quarter turn valves are designed by our own construction department and manufactured on our own. They are build for a long lifetime and maintenance-free operation.

The main advantages are:

• compact design

• constant torque-output

• modular design allows upgrade

   from hydraulic-acting to spring-acting

   and reverse

• various installation positions

• adjustable stroke limit

• no damage to oil pipes due to

   internal system piping

• same hydraulic connection over whole type series

• same hydraulic-control blocks for all sizes

• combined flanges acc. to ISO 5211

• NAMUR-connection for installation of all common limit switches /

   position indicators

• free shaft connection (customer related)

• emergency handoperation (mechanical) or through additional

   handpump via quick coupling

• torque range from 100 Nm up to 8.000 Nm
