EHPA Range Fail Safe Electro-Hydraulic Actuators

EHPA RANGE

With the combination of modern electrics and power of hydraulics, EHPA range is specifically well adapted for ESD valves such as high-pressure ball-valve or triple-offset butterfly valves.

 

WHAT IS FAILSAFE ?

The activation of an emergency signal triggers the immediate opening, closing or freeze of the backup device, without the need of any external power source and using a full mechanical spring return.
