Product Description

Direct Action Diaphragm Type Pressure Reducing Valve (GA200P)

Product Description

Brief Introduction.

This series reducing valve is direct action membrane type spring reducing valve, mainly composed of membrane, adjusting spring, valve seat and valve flap. It sense the change of lower stream pressure through the membrane and drive the valve flap, change and control the valve opening to realize the function of pressure reducing the regulating. Set the outlet pressure by adjusting the spring pressure through adjusting bolt The product works stably and flexibly. It is suitable for water supply piping of high buildings and assorting pilot valve for water power control valve.
