Pressure reducing valve is a valve in the body of the opening of the opening and closing of regulating the flow of medium, the medium pressure is reduced, at the same time with the aid of the role of the valve after pressure adjust the opening of open-close part, keep the valve after pressure within a certain range, under the condition of the inlet pressure changing, keep the outlet pressure within the scope of the set, protection appliances for production from then on.

Pressure reducing valve is composed of adjusting spring, diaphragm, piston, valve seat, disc and other parts. 
 

Pressure reducing valve from the main valve and needle valve, pilot valve, ball valve, and to take over the system composition, main body adopts the whole passage, once-through, streamlined design, and USES the diaphragm or piston type two kinds of structure.This product use set pressure regulating valve spring pressure and adjust the needle valve opening set outlet pressure, and by taking over the system and the control room of the feedback effect to stable outlet pressure.
 

Adjustable pressure regulator valve use needle valve, pilot valve for pressure control on our own efforts, do not need additional energy and other devices, easy maintenance, affected by the inlet pressure and flow rate is small, the pressure control of high accuracy, reduced pressure regulator is reliable.
