The axial flow check valve determines the opening and closing of the valve disc by the pressure difference between the inlet and outlet ends of the valve. Axial flow check valves can effectively prevent media backflow and ensure pipeline safety.

Characteristics of axial flow check valves:

1. The axial flow check valve is composed of a valve body, a guide body, an axial movement valve disc, and spring components. The product can effectively prevent media backflow. Ensure pipeline safety.

2. The valve body, disc, and tail cone are designed as streamlined channels, which have good fluid performance and reduce flow resistance and pressure.

3. Using high-performance spring material HT/INCONELX-750, it has excellent corrosion resistance, oxidation resistance, and excellent mechanical properties, ensuring that the spring operates in a state of long-term operation.

4. Silent operation to eliminate noise and water hammer in valve pipelines and ensure equipment and pipeline safety.

5. The opening and closing reactions are rapid, and the highly reliable pre compression spring enables the valve disc to respond quickly to changes in fluid pressure.

6. Compact structure, easy to install, suitable for both vertical and horizontal installation.

7. The valve adopts alloy steel overlay welding with a sealing surface, which is wear-resistant, corrosion-resistant, and has a long service life.

8. The pressure range of the valve is relatively wide.
