 Hydraulic actuators (1.3 MB)

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


Furthermore our hydraulic actuators are available in following special designs:


• with limit switch boxes: e.g. IP67, IP68, Ex

• spring closed / spring opened

• with emergency handoperation by intermediate gear box

• with application-specific control blocks

• with connection for emergency handpump

• separate installation of the control block

• operation in medium

• antimagnetic design
