Axial flow check valve is suitable for pressure class of 150Lb~600Lb(PN2.0~10.0MPa); Oil, chemical, natural gas and other working conditions with an operating temperature of -46~350°C to prevent the backflow of the medium. Its main structural features are:

1. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.

2. The sealing surface of valve disc and seat is surfacing with cobalt-based alloy, or the combination of non-metal and metal seal, the product has stable performance and long service life.

3. The end connection adopts welded end or flange connection, and the user can choose the connection mode according to the pipeline requirements to meet various engineering needs.

4. Linear flow design, low noise, energy saving, environmental protection, medium through the valve pressure loss is small.

5. Long service life, no blocking and reliable operation.

6. Low pressure seal and low pressure opening.

7. Zero leakage, the traditional check valve is incomparable.
