500X Pressure Relief Sustaining Valve consists of a main valve, pilot valve, and needle valve, ball valve, micro filter and pressure gauge to form a hydraulic control takeover system. Using hydraulic automatic operation, it can be used as a pressure relief valve and a pressure sustaining valve. When used as a pressure relief valve, it can maintain the pressure of the water supply line below the set safety value and maintain the water supply pressure upstream of the main valve. Its working principle is that when the pilot valve is adjusted to the pressure relief state, the water flows to the outlet through the needle valve, the main valve control room, the ball valve A the pilot valve and the ball valve B, and the main valve is in the open state at this time. When the inlet pressure exceeds the safety value set by the pilot valve, the pressure relief pilot valve will automatically open, and part of the water will be released through the ball valve C to relieve the pipeline pressure. Widely used in high-rise buildings, living areas and other water supply network systems and urban water supply projects.
