Description

DKV 500X pressure relief  valve is mainly used in fire protection or other water supply systems to prevent system overpressure or maintain the pressure of fire protection water supply system. It can also reduce the impact of water hammer after the fire pump is turned off, and is also used as a water hammer elimination device for large water supply systems. And a self-cleaning filter is installed at the inlet of the valve control system, which uses the fluid characteristics. Suspended particles with larger specific gravity and larger diameter will not enter the control system, ensuring smooth circulation of the system. It is also used in large-scale, so that the valve can operate safely and reliably. The system has stable operation, high strength, long service life, and is suitable for pipes with a diameter of less than 600.
