pressure reducing valve has many structural types
REDUCING VALVE has many structural types, in the past commonly are diaphragm-type, inner spring piston and so on. The basic principle of reducing valve is reducing water pressure with inner valve flow channel to local resistance, water pressure drop range is automatically adjusted by diaphragm connects with disc or inlet and outlet water pressure differential of piston, in recent years some new pressure REDUCING VALVES. have been produced, such as fixed ratio pressure reducing valve. its principle is using the floating piston water pressure ratio in the body to control the inlet and outlet end decompression is inversely proportional to inlet and outlet sides piston areas. Such reducing valves work smoothly without vibration; body without spring, so no spring corrosion, metal fatigue failure; good sealing performance without leaking, thus both reducing the dynamic pressure (water flows) also static pressure (flow rate is 0 ); particularly when decompression, it will not affect the water flow at the same time.
