The pilot piston steam pressure reducing valve is a pilot piston-type pressure reducing valve that consists of two main components: the main valve and the pilot valve. The main valve includes key parts such as the valve seat, valve disc, piston, cylinder liner, spring, and others. The pilot valve is primarily composed of the valve seat, valve disc, diaphragm, spring, and regulating spring.
By adjusting the spring pressure to set the outlet pressure, and using a diaphragm to sense changes in the outlet pressure, the valve drives the piston to regulate the flow area at the throttle position of the main valve. The pilot valve opens and closes to achieve pressure reduction and stabilization. This valve is widely used in steam pipelines and offers ultra-low pressure operation and pressure stabilization.

Scope of Application

This series of pressure reducing valves is suitable for use in various industries, including urban construction, chemicals, metallurgy, petroleum, pharmaceuticals, food, beverage, and environmental protection.
