The water pressure reducing valve produced by our professional manufacturer 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.

Product features:
1. Frost damage, in cold areas should pay attention to insulation
2. The water flow direction is wrong, the pressure reducing valve becomes a check valve, and the outlet pressure is 0.
3. If the spring is too tight to close, the pressure reducing valve will pass through P2 = P1
4. The leakage of the bypass pipe makes P2 deviate from the set value. In view of the superior reliability and durability of the pressure reducing valve, it is recommended not to install the bypass valve.
