Pressure reducing valve

Hydraulic control, no external driving force.

The main valve has only one moving part and the failure rate is low.

Diaphragm structure, no friction, high control sensitivity.The pressure behind the valve does not change with the change of the pressure in front of the valve.The pressure behind the valve does not change with the change of system flow;Good static pressure reduction effect;Wide range of pressure regulation after valve;

The adjustable pressure-reducing valve is a pilot pressure-reducing valve, which is composed of the main valve of the hydraulic control valve and the pressure-reducing pilot valve.The main valve outlet pressure change through the pilot valve amplification control of the main valve disc action;The work of the reduced pressure pilot valve is based on the balance between the force exerted by the spring downward to open the disc and the force exerted by the diaphragm upward to close the disc.When water is used at the back end of the main valve, the pressure of the guide valve spring is greater than the pressure acting on the lower end of the dowm.Guide valve open, the main valve cavity drain to the outside, the main valve open;When water is not used at the back end of the main valve, the back end pressure increases.Push the guide valve diaphragm upward to close the guide valve, thus closing the main valve and stabilizing the pressure at the back end at the set value;The water consumption of the back end of the main valve is different, so that the water pressure acting on the lower end of the diaphragm of the pilot valve is different.The opening of the pilot valve changes accordingly.In order to control the size of the main valve opening, so that the pressure at the back end is always kept at the set value;The pressure value set at the back of the valve can be adjusted by the adjusting screw on the pressure relief guide valve.
