Electro-hydraulic actuator EHS-D3

rotarydouble-actingISO

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 50,000 Nm. 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. Special Features Electro-hydraulic drive consisting of EHS Power Pack and double-acting drive Ready for immediate use Constant torque over the entire swivel angle Flange connection to DIN ISO 5211 Electrically powered Without external hydraulic lines Optical position indicator Adjustable end position Low oil quantity Maintenance-free Advantages Functional safety for SIL 2 to IEC 61508 Power supply 230V/400V Electric limit position switches / position indicator Integrated hydraulic emergency actuation (hand pump) possible Bus connection Modbus/Profibus, others upon request Explosion protection class: ATEX/IECEx Low temperature version: –55°C Submerged (upon request) IP67/IP68 Bronze version End positions adjustable on both sides (for ball valves)
