一、Purpose
It is a directly acting adjustable pressure reducing valve, uses the membrane hydraulic operation and can be mounted vertically or horizontally in the water supply, fire-fighting of other pure water system. The outlet pressure can be controlled at a relatively stable value within a certain range.
It is inner-thread connected, features an exquisite shape, easy installation etc. and is equipped with a built-in filter screen to make it integrally mounted and operated, without being blocked up with foreign matters and safer and more reliable.
