500x Relief Valve
500X Relief Valves are diaphragm-type hydraulic control valves designed to prevent system overpressure, reduce water hammer, and protect fire-fighting and water supply systems by automatically relieving excess pressure.
Overview
The 500X Relief Valve is a diaphragm-operated control valve primarily used in fire-fighting and water supply systems to prevent excessive pressure. It automatically opens to release excess pressure and closes once the system pressure returns to a safe preset level.
Working Principle
The valve operates using the pressure energy of the fluid itself. When system pressure exceeds the preset limit, the diaphragm moves to open the valve and discharge excess pressure. When pressure drops to normal levels, the valve closes smoothly to maintain system stability.
