Gearbox-type spiral stop valve, this structural hydraulic actuator has zero leakage, small volume, fast valve opening speed, and can be adapted to small-displacement electro-hydraulic power units. The entire system control logic and valve installation and debugging are simple. However, this actuator can only be applied to stop valves below DN250, and is not suitable for valves with large diameters.
