The Valve is composed of main valve, guide valve, needle valve, ball valve and pressure gauge. The pressure relief/Holding valve can effectively release the pressure beyond the safety setting value of the pilot valve in the pipeline to prevent damage to the pipeline and equipment due to overpressure. 500X pressure relief/hold valves are used primarily in fire or other water supply systems to prevent system overpressure or to maintain pressure in fire water supply systems. Fire pump closure can also reduce the impact of Water Hammer. Also used in large water supply system water hammer device. And the inlet of the valve control system is equipped with a clean filter net, which makes use of the characteristics of the fluid, so that the suspension particles with larger specific gravity and larger diameter will not enter the control system, thus ensuring the smooth circulation of the system, to enable safe and reliable operation of the valve. The system has stable action, high strength and long service life.
Product Overview:
1. Accurate and constant safe and stable pressure, once overpressure, pressure relief valve can be fully opened in time to relieve pressure.
2. Adjustable closing speed to eliminate pressure fluctuation.
3.The diaphragm drive mechanism minimizes the operating lag.
4. It can be installed in any position, without changing the pressure setting value or removed from the pipeline can be repaired and inspected.
