I. Working Principle
The high-pressure lift check valve is a new type of valve designed to prevent the backflow of liquids or gases. Its operation relies on fluid pressure to lift or lower the disc, enabling or blocking media flow. The disc and seat form a sealing interface to isolate the medium.
Key features:
Automatic Operation: Eliminates manual adjustments, offering efficient backflow prevention.
Superior Performance: Outperforms traditional check valves in high-pressure, high-temperature, high-viscosity, high-differential-pressure, scaling, crystallization, and coking conditions.
II. Design Features
High Reliability: Leak-resistant with robust disc-seat sealing.
High-Temperature & High-Pressure: Rated for up to 1000 bar and 500°C.
Smooth Lifting: Lightweight disc ensures low energy consumption and flexible movement.
Low Noise: Spacious chamber design minimizes flow velocity and noise.
Long Service Life: 3-12mm thick anti-corrosion coatings enhance durability.
III. Applications
Widely used in oil, chemical, metallurgical, and power industries for pipeline backflow protection, ensuring equipment safety and reliability.
