Product Description

First, YZ11X branch pipe pressure reducing valve - use and structural characteristics

YZ11X branch pipe pressure reducing valve is a direct acting diaphragm 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, settle valve disc, adjusting spring and other parts. Use the diaphragm to sense the downstream pressure change to drive the valve disc, change and control the opening of the valve to achieve pressure reduction and pressure regulation function. The outlet pressure value is set by adjusting the spring pressure. The pressure reducing valve of the branch pipe appropriately increases the diaphragm area and improves the sensitivity. The pressure reducing and stabilizing valve is stable and sensitive. The branch pipe pressure reducing valve is suitable for the branch pipe of high-rise building apartment building and residential area and the entry branch pipe of apartment and residence.
