Piston type pressure reducing valve

A piston type pressure reducing valve refers to a pressure reducing valve whose inlet overcurrent valve chamber and outlet control valve chamber are separated from the spring control chamber by a piston. The pressure control valve chamber automatically adjusts the pressure setting value behind the control valve by sensing the changes in the spring setting value and the pressure behind the valve. The working principle of piston type pressure reducing valve is based on the principles of fluid mechanics. By changing the throttling area, the flow rate and kinetic energy of the fluid are altered, resulting in different pressure losses and achieving the purpose of pressure reduction. The piston type pressure reducing valve produced by Shanghai Meiyanyi Pump Valve relies on the adjustment of the control and regulation system to balance the fluctuation of the pressure behind the valve with the spring force, keeping the pressure behind the valve constant within a certain error range. Piston type pressure reducing valve is suitable for high-temperature and high-pressure pipeline equipment.
