Check valves are used in high-pressure mains.
Check valves are installed in high-pressure lines and are designed to prevent a reverse-flow effect applied to the delivery line during development and repair of oil wells, oil production stimulation and cementing.
Advantages of our check valves:
-Maximum operating pressure 103.4 MPa.
-Steel component of a flap part is covered all over with a polymeric compound resistant to abrasive wear.
-Turning axis of the flap is upper than the port and do not interfere the flow.
-Shutdown is performed by gravity and under minimum change in pressure.
-The valve is repaired and maintained without removing it from mains.
-Able to ensure reliable operation having low sensitivity to medium contamination.
-Introduced materials help to use our check valve within acid treatment, cementing and fracturing.
