Direct acting pressure reducing valve

Product overview

The direct acting diaphragm pressure reducing valve consists of main valve and pilot valve. The main valve seat, main valve disc, piston, cylinder liner and spring of direct acting diaphragm pressure reducing valve are composed of valve seat, disc, diaphragm, spring and regulating spring. Through adjusting the spring pressure to set the outlet pressure, the diaphragm is used to sense the change of outlet pressure, and the pilot valve is opened and closed to drive the piston to adjust the size of the main valve throttling area, so as to realize the function of pressure reduction and pressure stabilization.

Product details

Product features
In the unloading structure, the pressure behind the valve does not change with the change of the pressure in front of the valve;
Wide range of pressure regulation, high precision and low noise;
Under the same pressure drop behind the valve, the valve has a larger flow rate;
The valve disc surface with moderate gradient has good stability at small opening;
Diaphragm structure, waterproof and scale proof, no jamming during operation;
Stainless steel material, imported diaphragm, long service life;
The internal structure is simple and easy to maintain.
