Fire valve series
Pressure relief valve is used in water system pipeline to adjust the pressure ratio between the water supply chamber and the working chamber pipeline according to the need and keep the same automatically. The valve operates smoothly and reliably, not only reduces the dynamic pressure but also reduces the static pressure. The pressure of the working chamber can be kept constant when the valve is adjusted. The valve is simple in structure, light in weight and convenient in operation and maintenance.
