The piston type adjustable pressure reducing regulator is a special valve that is installed on the pipeline of the water supply and drainage system of high-rise buildings to reduce the inlet pressure to a certain required outlet pressure. The valve relies on its own energy to keep the outlet pressure stable at the set plant, that is, the outlet pressure does not change due to changes in the inlet pressure and flow rate, and the inlet of the valve control system is equipped with a self-cleaning filter, using the characteristics of the body, so that the suspended particles with larger gravity and larger diameter will not enter the control system to ensure that the system circulation is unimpeded. Make the valve to operate safely and reliably. The system has stable operation, high strength and long service life. Piston type for valves greater than 450 caliber.
