Product Description
200X pressure reducing valve is an intelligent valve that uses the self energy of the medium to regulate and control the pressure in pipes. The 200X pressure reducing valve can be used in domestic water supply,fire fighting water supply and other industrial water supply systems. The outlet pressure of the main valve can be regulated through the adjustment of the pressure reducing valve; the outlet pressure does not vary along with the inlet pressure and inlet flow. Accordingly, the outlet pressure can be safely and reliably maintained at a preset value and the preset value can be adjusted according to actual needs to obtain your pressure reducing goal. This valve is precise in pressure reduction, stable in performance, safe, reliable, easy, convenient to
install and adjust and offers a long service life.

working principle
The pressure reducing valve is an essential accessory of the pneumatic control valve, the main function is to reduce the pressure of the air source
Pressure and stabilize to a fixed value, so that the regulating valve can obtain a stable air source power for regulating control. According to the structure, it can be divided into diaphragm type, spring diaphragm type, piston type, lever type and bellows type; according to the number of valve seats can be divided into single seat type and double seat type; according to the position of the valve disc, it can be divided into positive acting type And reactionary.
main effect
The working principle of the pressure reducing valve is to reduce the water pressure by the local resistance of the flow channel in the valve to the water flow. The range of the water pressure drop is automatically adjusted by the diaphragm connecting the valve flap or the water pressure difference between the inlet and outlet on both sides of the piston. In recent years, some new pressure reducing valves have appeared, such as fixed ratio pressure reducing valves. The principle of constant ratio pressure reduction is to use the water pressure ratio of the floating piston in the valve body to control, and the pressure reduction ratio at the inlet and outlet ends is inversely proportional to the piston area ratio at the inlet and outlet sides. This kind of pressure reducing valve works smoothly and without vibration; there is no spring in the valve body, so there is no concern about spring corrosion and metal fatigue failure; the sealing performance is good and does not leak, so it reduces both dynamic pressure (when water flows) and static pressure (flow rate is 0 o'clock); especially when decompression does not affect the water flow.
