Product Name:YZ11X branch pressure reducing valve
Product Introduction
Stainless steel branch pressure reducing valveYZ11X internal thread branch pressure reducing valve/brass branch pressure reducing valve/branch water pressure reducing valve/residential building pressure reducing valve/community branch pressure reducing valveIt is mainly used in various building water supply systems, fire protection systems, central air conditioning systems, heating systems, etc. It is commonly used for branch pressure reduction, which can make the distribution of water supply pressure more balanced, avoid partial water supply overpressure, 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 water and other water appliances.
Product Features:
1. Adopting a direct acting diaphragm structure, the internal structure is very simple, unobstructed, reliable in performance, and durable.
2. Resistant to dirt and water stains, no need for filters or bypass pipes, extremely simple piping, can save a lot of space and piping costs.
3. The outlet pressure is precisely adjustable, and 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).
4. Excellent hydraulic characteristics, low pressure loss, and a pressure reduction ratio of over 10:1.
5. Can meet various pressure reduction requirements, especially suitable for branch pressure reduction systems.
working principle(image):
1. The outlet pressure acts on the bottom surface of the diaphragm and the valve disc. When it exceeds the set value of the spring, it compresses the spring and causes the valve disc to close.
2. As long as there is no water flow downstream, the outlet pressure will remain at the set value (with a change of only 8% of the inlet pressure change).
3. When downstream water is used, the outlet pressure drops, and the spring pushes open the diaphragm, opening the pressure reducing valve.
4. After a continuous flow of water, the opening of the pressure reducing valve produces a self damping effect, making the opening and closing actions tend to be stable.

Possible causes of malfunction:
1. Frost damage requires attention to insulation in cold regions.
2. The water flow direction is installed incorrectly, the pressure reducing valve becomes a check valve, and the outlet pressure is 0.
3. The spring is too tight to close, and the pressure reducing valve will be directly connected to P2=P1.
4. The bypass pipe is leaking, causing P2 to deviate from the set value.
5. Considering the good reliability and durability of this pressure reducing valve, it is recommended not to install a brightness tube.
