The branch pressure reducing valve adopts a direct acting diaphragm structure, with a simple internal structure, no jamming, reliable performance, and durability. Pressure reducing valves are resistant to dirt and water stains, do not require filters or bypass pipes, have simple piping, and can save a lot of space and piping costs. The outlet pressure of the branch pressure reducing valve can be adjusted. In general, it can be assumed that the outlet pressure is not affected by the inlet pressure (the change in outlet pressure is 8% of △ P1). The pressure reducing valve has excellent hydraulic characteristics, with low pressure loss and a pressure reduction ratio of over 10:1. It can meet various pressure reduction requirements and is suitable for branch pressure reduction systems.
Branch pressure reducing valves are mainly used in various building water supply systems, fire protection systems, air conditioning systems, heating systems, etc. It is used for branch pressure reduction, and branch pressure reducing valves can make the distribution of water supply pressure more balanced, avoid partial water supply pressure, and optimize the water supply zoning of high-rise buildings. It can replace zone frequency and variable speed water pumps, and can replace zone water pumps in fire water supply systems. It is used in household water supply systems and can protect all faucets and other water appliances.
