The Pressure Relief Valve for fire protection systems is designed with a compact structure that requires no conduit, making transportation, installation, maintenance, and repairs easier and more efficient. It automatically releases pressure when the pipeline pressure exceeds the preset limit, helping to protect the system from over-pressure conditions. The valve is suitable for use with general liquids and gases and can be conveniently mounted either horizontally or vertically to suit different installation requirements. It offers a wide capacity range, enabling it to handle varying local water supply pressures and to be adjusted according to specific pump specifications. The pilot adjustment feature allows for simple and accurate calibration of the pressure setting, while the valve’s design ensures easy maintenance, with maintenance kits available upon request.
