    1. YZ11X branch pipe pressure reducing valve-purpose and structural characteristics

    YZ11X branch pipe pressure reducing valve is a direct-acting membrane spring pressure reducing valve, which is designed and manufactured on the basis of absorbing the advantages of similar foreign products. It is mainly composed of diaphragm, flap valve, adjusting spring and other parts. Use the diaphragm to sense the downstream pressure change to drive the valve flap, change and control the valve opening to realize the pressure reducing and stabilizing function. The outlet pressure value is set by adjusting the spring pressure. The branch pressure reducing valve appropriately enlarges the diaphragm area and improves the sensitivity. Decompression and stabilization are stable and sensitive. The branch pressure reducing valve is suitable for the branch pipelines of high-rise apartment buildings and residential areas, as well as the household branch pipes of apartments and houses.
