500X Hydraulic Pressure Relief /Pressure holding control valve Diaphragm / PistonType Flanged End

 

Product overview:

 

 

The 500X pressure relief / pressure holding valve is primarily used in fire or other water supply systems to prevent system overpressure or to maintain pressure on the fire water supply system. The impact of the water hammer can also be reduced after the fire pump is turned off. Also used in water hammer devices for large water supply systems. And the cleaning control screen is installed at the inlet of the valve control system. The fluid characteristics are used to make the suspended particles with larger specific gravity and larger diameter not enter the control system, ensuring unobstructed circulation of the system and enabling the 500X pressure relief / pressure holding valve to operate safely and reliably. The system operates smoothly, with high strength and long service life.

Working principle:

 

 1.As a pressure relief valve: when the pressure relief/pressure holding pilot valve is adjusted to the pressure relief state, the water flows through the needle valve, the main valve control chamber, the ball valve A, the pressure relief/pressure holding pilot valve, and the ball valve B to the outlet. The main valve is open. When the inlet pressure exceeds the safe value set by the pressure relief/pressure holding pilot valve, the pressure relief pilot valve will automatically open, and part of the water is discharged through the ball valve C to relieve the pressure of the pipeline. The pressure relief valve automatically closes when the pressure returns to a safe value. When making a pressure relief valve, each ball valve is normally open.


2. As the holding pressure valve: When the pressure relief/pressure holding pilot valve is adjusted to the holding pressure state, the pilot valve is closed as long as the main valve inlet water pressure is lower than the pilot valve setting value. The main control room is boosted and the main valve is closed. When the upstream supply pressure of the main valve exceeds the set pressure of the pilot valve, the holding pilot valve can be opened, the water in the control chamber is discharged to the outlet through the ball valve, and the main valve of the control chamber is opened, and the water supply is started, that is, the upstream water pressure is maintained. When used as a pressure holding valve, the ball valve C is normally closed or replaced with a wire plug.

 

 

Structural features and Applications:

 

The 500X pressure relief/pressure valve consists of a main valve, a pressure relief/pressure holding pilot needle valve, a ball valve, a microfilter and a pressure gauge to form a hydraulic control takeover system. It can be used as a pressure relief valve or as a pressure holding valve by hydraulic automatic operation. When used as a pressure relief valve, the water supply line pressure can be maintained below the set safety value; for the pressure holding valve, the upstream water pressure of the main valve can be maintained above the set value to maintain the upstream supply pressure of the main valve.

 

500X pressure relief / pressure holding valve utilizes hydraulic self-power control, does not require other devices and energy, and is easy to maintain, with multiple valves.

 

500X pressure relief / pressure holding valve are widely used in high-rise buildings, living areas and other water supply pipe network systems and urban water supply projects.
