Check valve
The check valve is used to isolate well fluids and prevent backflow. It is installed in high-pressure pipelines to stop liquid from flowing backward, with the flap automatically closing to block reverse flow. Designed and produced according to API-6A standards.
Product Features
1. High Structural Strength: Made from high-strength alloy steel.
2. Easy Disassembly: Butt-welded ends for easy installation and removal from pipelines.
3. Good Sealing: The flap surface is coated with hydrogenated nitrile rubber for excellent sealing.
4. Long Service Life: Designed for long life under high-pressure conditions.
5. Convenient Maintenance: Daily maintenance can be performed without removing the valve from the high-pressure pipeline.
6. Environmental Adaptability: Suitable for both standard and sulfurous gas operations.
