EHS-D3 Series

Plug & Play – ready-to-use actuator solution for quarter-turn valves.

The electro-hydraulic actuators of the EHS-D3 series combine the advantages of electric and hydraulic actuator technology and are ready for immediate commissioning. A combination of EHS Power Pack, paired with a hydraulic STK actuator provides a powerful unit that is electrically controlled and generates torques up to 50,000Nm. It contains a closed hydraulic system, which does not require any external hydraulic lines and can be used flexibly due to its maintenance-free design. A wide range of sensors and modules are available for integration into Industrial 4.0 and IoT systems.

Whether ball valve or butterfly valve, dry or wet installed, the EHS-D3 is available in a wide range of designs.
