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.

Product Parameters

1. Specifications: 2″, 3″
2. Pressure: 105 MPa
3. Material Levels: EE
4. Temperature Ranges: PU (-29-121°C)
5. Product Specification Levels: PSL1~PSL3

Operating parameters

When fluid flows in the direction indicated by the arrow, it pushes the valve disc open, allowing fluid to pass through. Conversely, if the flow reverses, the disc covers the valve seat, creating a seal.
