Gas Over-oil Hydraulic Actuator

GVK's GPA-series pipeline actuators are powered by pipeline gas. Our hydraulic scotch-yoke quarter-turn actuator acts as the valve prime mover, and we specialize in designing gas-hydraulic actuators to various specifications. Each actuator includes a manual override and a separate hydraulic override cylinder for maintaining high-pressure gas and hydraulic fluid separation, allowing for seal replacement without actuator removal and enabling manual operation during disassembly. The gas control manifold features dependable pilot-operated poppet valves for easy remote operation.
