Electro Hydraulic Actuator

Product Info

ProControl EHS & EHD series actuators are composed by a SHS or SHD actuator combined with an electro hydraulic power unit.


ProControl electro hydraulic system is suitable for several applications, such as on/off, total modulating service and partial stroke testing. It can also achieve an ultra-fast fail safe stroke within < 200 MS by means of the special integrated hydraulic discharging system, complete with damping device to absorb the shock in the last part of the stroke. ProControl can supply central hydraulic units designed to operate any number of actuators/valves from a single control centre. ProControl’s electro hydraulic actuators give client peace of mind due to the reliability of the product due to complete independence from pipeline pressure as power source
