Product Description

Water pressure reducing valve
This series of pressure reducing valve is a direct acting diaphragm spring pressure reducing valve. It is mainly composed of adjusting spring, diaphragm, piston, seat, valve disc and other parts. The diaphragm directly senses the downstream pressure to drive the valve disc, and controls the opening of the valve disc to complete the function of reducing pressure and regulating pressure. In the cold and hot water supply system of urban buildings and high-rise buildings, it can replace the conventional partition water pipe and save equipment. It can also play the role of reducing pressure and stabilizing pressure in the usual cold and hot water pipe network. This product has stable pressure regulating and stabilizing action, and is suitable for water and non-corrosive liquid medium pipelines.
