Name:Pressure reducing DN400 hydraulic control valve
The remote control float valve is composed of the main valve of the hydraulic control valve and the float switch and piping. The main function is to control the liquid level of the pool or the elevated water tower. The valve is installed at the entrance of the pool or the elevated water tower.

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.
