The water pressure reducing valve is mainly used in various building water supply systems, fire fighting systems, central air conditioning systems, heating systems, etc. it is used for branch pipeline pressure reduction, which can make the water supply pressure distribution more balanced, avoid partial water supply over-pressure, optimize the water supply division of high-rise buildings. It can replace the frequency modulation variable speed pump in the partition, and can replace the partition pump in the fire water supply system, and used in domestic water supply system to protect all taps and other water appliances.

1. Direct acting diaphragm structure is adopted, with simple internal structure, no jamming, reliable performance and durability.
2. It is dirt resistant and water-proof. It does not need bypass pipe, the piping is very simple and can save a lot of space and piping cost.
3. The outlet pressure is precisely adjustable. In general, it can be considered that the outlet pressure is not affected by the inlet pressure (the variation of the outlet pressure is 8% of △ P1)
4. Excellent hydraulic characteristics, small pressure loss, decompression ratio of more than 10:1.
5. It can meet various decompression requirements, especially suitable for branch decompression system.
