A YZ11X manifold valve -- Application and structure
YZ11X branch reducing valve is a direct acting type diaphragm pressure reducing valve, absorbing the advantages of similar foreign products based on the design and manufacture. Mainly by the diaphragm, step disc, springs and other parts adjust. Using the diaphragm sensing downstream pressure change valve, change and control valve opening to achieve the function of reducing pressure. By adjusting the spring pressure to set the outlet pressure value. Manifold valve due to the area of the diaphragm, improved sensitivity. Pressure relief stable, sensitive. Branch pipe manifold valve is suitable for high-rise apartment buildings and residential and residential apartments, home use branch.
