The role of SUN pressure reducing valve

The principle of pressure reducing valve is to rely on the valve flow path to the water flow of local resistance to reduce water pressure, the range of water pressure drop by the membrane connected to the valve or piston on both sides of the import and export of water pressure difference is automatically adjusted. The principle of fixed ratio pressure reduction is the use of floating piston in the valve body of the water pressure ratio control, inlet and outlet end of the pressure reduction ratio and the import and export side of the piston area ratio is inversely proportional. This pressure reducing valve works smoothly without vibration; no spring in the valve body, so there is no spring corrosion, metal fatigue failure; good sealing performance without leakage, thus reducing both dynamic pressure (water flow) and static pressure (flow rate of 0); especially in the reduction of pressure at the same time does not affect the water flow.
