The 500X pressure relief/pressure holding valve is mainly used in fire protection or other water supply systems to prevent system overpressure or maintain the pressure of the fire protection water supply system. Ensure the unobstructed circulation of the system to enable the valves to operate safely and reliably

Product Description
The 500X pressure reducing valve is a pilot-operated, diaphragm type pressure reducing valve. Its core function is to reduce and stabilize the fluctuating high inlet pressure at a set, lower and stable outlet pressure, regardless of how the inlet pressure changes or how the downstream flow demand alters.
The 500X pressure relief/pressure holding valve is composed of a main valve, a pressure relief/pressure holding pilot valve, a needle valve, a ball valve, and a pressure gauge. It is automatically operated by a hydraulic control connection system and can be used as both a pressure relief valve and a pressure holding valve. When used as a pressure relief valve, it can maintain the pressure of the water supply line below the set safety value. It can be used as a pressure-holding valve to maintain the water pressure upstream of the main valve above the set value and keep the water supply pressure upstream of the main valve. It is an upgraded and replaced product of the spring-loaded safety valve.
Features
• High-precision control
• Wide pressure reduction ratio: Capable of handling high inlet pressure and reducing it to a very low outlet pressure
• Flow independence: Within a certain range of flow variation, it can automatically adjust the opening degree to maintain the outlet pressure basically constant.
• Reduce pressure without reducing flow
• Convenient for maintenance
