Profile ：As for the water supply pressure control systems in high-rise and super high-rise buildings, when the pressure reducing ratio is greater than 3:1, it would occur cavitation at the valve seat. The cavitation does not only shorten the service life of pressure reducing valve, causing fluctuation of water supply pressure and endangering water supply safety, but also it will cause unbearable noise to impact people’s working and living.

Application： The valve is mainly used in the water supply pressure control systems in high-rise and super high-rise buildings, in which the pressure reducing ratio is greater than 3:1.

1. The way that water flows through the pressure reducing valve from upside to underside can avoid the cavitation occurring at the seal space between the seat and the seal ring of disc when water flows in high speed, thereby preventing the seal space from damaging.

2. An anti-cavitation shield has been set up below the valve seat. Through oval slots on the anti-cavitation shield, the pressure reducing valve could make pressure reduce possible. Even the cavitation happens at the time when the pressure reducing valve works under a low flow state, it only occurs inside the anti-cavitation shield, thus preventing the valve seat from damaging.

3. The cavitation shield is made of stainless steel with high strength of extension and anti-cavitation abilities. With enough anti-cavitation metal allowance preserved, the service life of pressure reducing valve could be well ensured.

4. The anti-cavitation large pressure differential adjustable pressure reducing valve has a unique design structure. Compared with the traditional pressure reducing valves, it has filtering function and large pressure reducing ratio which can reach more than 9:1, as well as anti-cavitation ability, small noise, reliable performance, and long service life characteristics.

5. Self-equipped with strainer to block the debris in the pipe.
