Features
1. Welding connection, reliable sealing
The valve body inlet and outlet come with standard sized welded short pipes, which can be directly welded to the pipeline. High connection strength, no leakage risk, able to effectively withstand system thermal stress and mechanical vibration.
2. Spring micro opening structure
Adopting a direct load spring mechanism and a micro opening valve disc, the action response is fast, the opening height is small, and it is suitable for liquid media or situations requiring small displacement pressure relief.
3. Directly machining the sealing surface of the valve body ("W" type)
The sealing surface is directly processed or welded from the valve body material, with a sturdy structure and good economy, suitable for non corrosive media such as water, steam, and oil.
4. Compact structure, adjustable pressure
The overall design is compact. By adjusting the screw, the spring preload can be limited, thereby setting the accurate opening pressure (set pressure) to meet the safety requirements of different systems.
5. Suitable for harsh environmentsWelding connections eliminate the risk of flange gasket aging or thread corrosion, making them more suitable for high-temperature, high-pressure pipelines or harsh environments such as outdoor and vibration.
