Pressure Relief And Anti Vacuum Valves

Pressure relief and anti-vacuum valves are essential components for any piping system that handles pressurized fluids. These valves are designed to prevent excessive pressure buildup, which can damage equipment or cause dangerous situations. The primary function is to discharge fluid when the pressure in the system exceeds a predetermined level. Similarly, the anti-vacuum feature ensures that there is no negative pressure in the system, which can damage or collapse the pipeline.

Today, with the increasing demand for safe and reliable systems,  and anti-vacuum valves have become crucial in various industries such as pharmaceuticals, petrochemicals, food and beverage, and water treatment. The trend in the industry is towards the development of valves that are more accurate, efficient and durable, providing superior performance and longer service life. Advanced materials and manufacturing technologies are being used to improve the quality and reliability of these valves, ensuring the highest degree of safety and environmental protection.

Disassembly and assembly

Disassembly

●Unscrew the valve bonnet (9) in anti-clockwise direction by inner square wrench, disassemble the spring (8), up valve plate (6), lower valve plate (4) and the connecting parts.

●Disassembly clamp spring (7) and remove spring (10).

●Disassembly lower valve plate (4) and remove sealing gasket (5) (The pressure from spring (10), (8) were released)

Pressure relief and anti vacuum valves Overview:

Installed in a normal non-negative pressure system, the valve automatically opens when the container and system's relief valve is not open and a negative pressure is generated. The negative pressure safety valve is suitable for various containers and equipment with PN1.0～2.5MPa and working temperature≤200°C, and the opening pressure is -0.001～-0.09MPa. Different materials can be used for air, steam, sexual media, and other media.
