DVG Automation designs and manufactures instrumentation systems and skid mounted units that provide the motive power to drive hydraulic actuator. DVG Automation offer Electro Hydraulic Units designed to operate from a single source either one or a number of valve actuators, singularly or contemporaneously, guaranteeing the correct pressure and volume to stroke the actuators.
DVG Automation Electro Hydraulic Units are the right solution for emergency shutdown and fail safe application. In case of loss of electrical power, the accumulator maintains reserve hydraulic power for a defined number of piston strokes.
