The pressure reducing valve is a control valve driven by hydraulic pressure and controlled by pilot valve.
No matter how the flow rate or the pressure in front of the valve fluctuates and changes, the valve can reduce the high pressure in front of the valve to the low pressure behind the valve and keep stable; even if there is no water for users, the pressure at the outlet can be kept stable
