Electro Hydraulic Series
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. These unit are a total closed loop system and have no exhaust to atmosphere.
