Diaphragm safety relief - pressure valve QP742X

Structure and use

 

Installed in high-rise buildings, fire water supply systems and other water supply systems, when the pressure in the water supply pipeline exceeds the pressure set pressure, the pressure relief valve automatically opens the rapid pressure relief, protects the safety of the pipeline, and can also be used as a pressure-holding valve. Use to ensure the water supply pressure upstream of the main valve. It can accurately maintain the constant safety setting pressure. Once overpressure, the pressure relief valve opens quickly, relieves pressure in time, and the shutdown is stable and reliable, eliminating the residual pressure.
