Vacuum Regulator Valve

    Adjustable pressure reducing valve is a valve controlled by water pressure. The hydraulic control valve consists of a main valve and its attached pipes, guide valves, needle valves, ball valve, and pressure gauges. According to different usage purposes, functions, and locations, it can be evolved into remote control float valves, pressure reducing valves, slow closing check valve, flow control valves, pressure relief valves, hydraulic electric control valves, water pump control valve, etc.

working principle
    Adjustable pressure reducing valves typically consist of a main valve and one or more auxiliary valves (such as pilot valves). By adjusting the auxiliary valve, the pressure distribution inside the main valve can be changed, thereby controlling the opening degree of the main valve and achieving precise adjustment of the outlet pressure. In some designs, the pressure reducing valve is also equipped with a spring adjustment device, allowing users to manually adjust the outlet pressure to the desired level

Installation and usage tips

• During installation, it should be ensured that the direction of the valve is consistent with the direction of fluid flow to ensure the normal operation of the valve.
• If the water quality is impure, a filter should be installed upstream of the pressure reducing valve to prevent impurities from entering the interior of the valve.
• To prevent overpressure behind the valve, a safety valve should be installed at an appropriate distance.
• When using a pressure reducing valve in a hot water system, a check valve should be installed between the pressure reducing valve and the expansion tank to prevent the impact of hot water reflux or pressure fluctuations on the pressure reducing valve
