    500X Pressure Relief And Holding Valve

    Product overview

    500X Pressure relief/holding pressure valve is mainly used for fire protection or other water supply systems to prevent systems over pressure or maintain the water supply pressure of fire protection system. Closing of the fire protection pumps can reduce the impact of water hammer. The valve is also used for eliminating water hammer devices of large-scale water supply system. What's more, at the inlet of valve control system is a self-cleaning filter which makes suspended particles with larger proportion and diameter not enter the control system by using characteristic of flow to ensure smooth system circulation so that the valve can operate safely and reliably. It has stable system operation, high strength, long service life. The valve is applicable to pipelines of less than DN600mm.

    Product details

    Product Features


    500X Pressure relief and holding valve is mainly used in fire fighting or other water supply systems to prevent system overpressure or maintain the pressure of fire water supply system. After the fire pump is shut down, the impact of water hammer can be reduced. It is also used for water hammer device of large water supply system. Moreover, a clean filter screen is installed at the inlet of the valve control system, which makes use of the fluid characteristics to prevent the suspended particles with larger specific gravity and larger diameter from entering the control system, so as to ensure the smooth circulation of the system and ensure the safe and reliable operation of the valve. The system has the advantages of stable operation, high strength and long service life.
    Hydraulic control connection system. Hydraulic automatic operation can be used as pressure relief valve and pressure holding valve. When used as a pressure relief valve, it can maintain the water supply pressure below the set safety value; when used as a pressure holding valve, it can maintain the upstream water pressure of the main valve above the set value and maintain the water supply pressure upstream of the main valve.
    This product uses hydraulic self-control, does not need other devices and energy, maintenance is simple, one valve multi-purpose. This series of valve products are widely used in high-rise buildings, living areas and other water supply network systems and urban water supply projects.
