                The 500X pressure relief/holding valve is mainly used in fire fighting or other water supply systems to prevent system overpressure or maintain pressure in fire fighting water supply systems. After the fire pump is closed, it can also reduce the impact of the water hammer. It is also used for water hammer devices in large water supply systems. And the valve control system is equipped with a clean filter at the entrance, the use of fluid characteristics, so that the proportion of larger, larger diameter suspended particles will not enter the control system to ensure smooth circulation of the system, so that the valve can operate safely and reliably. The system has stable movement, high strength and long service life.

                Structural features and uses

                The 500X relief/holding valve consists of a main valve, a relief/holding valve needle valve, a ball valve, a microfilter and a pressure gauge to form a hydraulic control nozzle system. Using hydraulic automatic operation, it can be used as pressure relief valve and can also be used as holding valve. When used as relief valve, the water supply pressure can be maintained below the set safety value; when used as pressure holding valve, the upstream water pressure of the main valve can be maintained above the set value, and the upstream water supply pressure of the main valve can be maintained.

                This product uses hydraulic self-control, no need of other devices and energy, simple maintenance, and multi use of one valve.

                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.

                Working principle

                1. Pressure relief valve: When the pressure relief / pressure holding guide valve is adjusted to the pressure relief state, water flows through the needle valve, main valve control room, ball valve A, pressure relief / pressure holding guide valve, ball valve B to the outlet, at this time the main valve is in the open state. When the inlet pressure exceeds the safety value set by the pressure relief/pressure holding guide valve, the pressure relief guide valve will automatically open, and part of the water will be discharged through the ball valve C to make the pipeline pressure relief. When the pressure is restored to the safe value, the relief valve automatically closes. When the relief valve is used, the ball valves are always open.

                2. Pressure-holding valve: When the relief/pressure-holding guide valve is adjusted to the pressure-holding state, as long as the inlet water pressure of the main valve is lower than the set value of the pilot valve, the pilot valve is closed. The main control room is boosted and the main valve is closed. When the upstream water supply pressure of the main valve exceeds the set pressure of the pilot valve, the pressure holding guide valve can be opened. The water in the control room is discharged through the ball valve to the outlet, and the pressure reducing main valve in the control room is opened to start the water supply, that is, the upstream water pressure is maintained. When holding the pressure valve, the ball valve C is usually closed or replaced with a plug.
