EDHA angular stroke double acting electrohydraulic execution

EDHA angular stroke double acting electrohydraulic execution / EDHA

Overview : The Angle stroke double-acting electrohydraulic actuator (EDHA) integrates the hydraulic micro power unit and hydraulic actuator as a high-end executive part, which has the convenience of control. There is no need to connect the external tubing, only the power supply can be provided to carry out the work, and the remote centralized control of the valve can be realized through the network. It is mainly used for opening and closing of valves in water tank, oil tank, bilge and other pipelines of all ship types.
Features :

Set electrical control, hydraulic power and mechanical transmission in one, with high reliability and easy to install and use;

Compared with the electric actuator, the product has smaller volume and larger output torque at the same power.

Compared with hydraulic actuators, this product is self-contained, integrates hydraulic power unit, saves the laying of hydraulic pump station and hydraulic pipeline, saves costs, and improves the efficiency of installation and maintenance.

The electro-hydraulic driver covers a variety of control modes, such as switching volume, analog volume, CAN communication, etc., to meet customers' different requirements for control modes;

The electro-hydraulic actuator is equipped with on-site emergency operation function. In emergency case (failure or power failure), the valve can be opened and closed by moving the hand pressure pump.
