Overview
The G500X groove pressure relief valve is a key safety protection valve independently developed and produced by our factory based on the digestion and absorption of international advanced technology, combined with the actual working conditions in China. It integrates the functions of a safety valve, a pressure relief valve, and a pressure regulating valve, and can reliably achieve comprehensive control of system overpressure automatic release, pressure stability, and safety protection. This valve can effectively eliminate abnormal pressure increases in the system caused by pump unit start stop, valve misoperation, or temperature changes, avoiding damage to pipelines and equipment due to overpressure. The valve adopts a pilot controlled structure and a precision pressure feedback system, which dynamically monitors and automatically adjusts the pipeline pressure by setting precise discharge pressure and continuous discharge flow rate. It is particularly suitable for pressure protection of high-rise building water supply systems, fire water supply networks, industrial circulating water systems, and long-distance water transmission pipelines. This valve has the advantages of sensitive response, accurate pressure relief, stable operation, reliable reset, and easy maintenance. It is an important device to ensure the safe, stable, and long-term operation of various pressure pipeline systems. Welcome to consult and purchase.

feature
The working principle of G500X groove pressure relief valve is to use the change of pressure in the sensing pipeline system as the control signal, and use the pilot pressure feedback system to drive the opening and closing action of the main valve. When the pressure inside the pipeline is within the normal set range, the main valve remains closed; When the system pressure rises due to reasons and exceeds the preset safety value, the pilot valve automatically opens, releasing the pressure in the control chamber of the main valve, causing the main valve disc to quickly open under the pressure of the medium, and discharging excess medium in an orderly manner to the low-pressure side or atmosphere, thereby achieving rapid pressure relief. When the system pressure returns to below the safe set value, the pilot valve will automatically close, the control chamber will rebuild pressure, and the main valve will be driven to close smoothly. This process achieves overpressure protection and pressure stability control of the pipeline system through continuous pressure monitoring and dynamic adjustment, ensuring that the pipeline network and equipment always operate within a safe pressure range.
