Decompression valves is composed by
the main valve, needle valve, pilot valve, ball valve and piezometer, etc.
Decompression valves is controled by polit valve and automatically drived by the pressure difference of the Upstream and downstream of pipline.
Valve is used for pressure relief for circulating system of high-rise structures, avoiding system danger due to excessively high hydraulic pressure.
It maintains upstream water pressure at preset pressure and ensure water supply.
