Diaphragm adjustable pressure reducing valve is installed in the high-rise building water supply and drainage pipeline system, special valve inlet pressure Zang to a desired outlet pressure. Diaphragm type adjustable pressure relief valve, diaphragm type pressure regulator valve, adjustable pressure relief valve. The valve outlet pressure to rely on its own energy remained stable in the set value, the outlet pressure is not due to changes in inlet pressure and flow and the change of imports and the valve control system is provided with a self cleaning filter, using the fluid characteristics, the proportion of larger suspended particles of larger diameter will not enter the control system. To ensure the circulation system smoothly. The valve can run safely and reliably. The system is sensitive, and the service life is long.
