Overview

Direct Acting Bellows Sealed Pressure Reducing Valve

Product Details

Structural Characteristic&Purpose.

This series reducing valve is Direct acting bellows pressure reducing valve, It is mainly composed of bellows, adjusting spring, valve seat and valve flap. It sense the change of lower stream pressure through the bellows 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 piping of gas and liquid medium.
