200MThe water control multi orifice pressure reducing valve has the advantages of compact structure, multi-stage internal pressure reduction, strong cavitation resistance, long service life, low noise and low vibration. It is widely used in construction systems, high-grade hotels, office buildings and other occasions with strict environmental requirements, and also can be used in high-pressure differential occasions such as cooling and water supply of hydropower stations.

1. Super anti cavitation ability: the valve uses collision energy dissipation, and the special squirrel cage structure ensures that the valve can still operate safely even under super cavitation conditions, without the minimum cavitation index limit.
2. Low noise: there is a special noise reduction structure inside, which can maintain a low noise level even if the valve is in the largest energy dissipation mine.
3. Long service life: valve accessories are made of high-performance materials, the diaphragm is made of high-strength nylon rubber, as well as the valve's super strong cavitation resistance, so that the valve has an ultra long service life.
4. Stable outlet pressure: it has good anti vibration ability and does not change with the change of inlet pressure and flow rate.
