UPVC Safety Valve

UPVC Safety Valve

The valve is mainly composed of a seat, valve cover, diaphragm, spring, pressure adjustment screw, etc. There are two concentric cavities in the seat, and there is a diaphragm between the two cavities. The spring is above the diaphragm, exerting a certain pressure on the diaphragm, pressing the diaphragm and separate the two cavities. When it working, the fluid enters from a cavity, the pressure rises, and the pressure acting on the diaphragm rises accordingly. When the pressure exceeds the pressure which set by the spring, the diaphragm is jacked up, two cavities are connected, and the liquid flows out of the other port. When the system pressure is reduced below the set pressure, the diaphragm closes, cutting off the passage of fluid. The valve can be used as either a safety valve or a back pressure valve.

Features of UPVC Safety Valve
1.Release the pipeline pressure to ensure the stability of the system pressure when using upvc valves;
2.Protect the safety of the pump and the normal operation of the system;
3.Used in conjunction with a pulse damper to reduce the harm of water hammer to the system and achieve superior low-vibration adjustment effects;
4.Reduce the peak value of flow rate fluctuations and protect the pipeline system from pressure fluctuations;
5.The diaphragm adopts advanced PTFE+rubber compound technology, which is suitable for almost all corrosive fluids, and the sealing is reliable and leak-free.
