API 6D Axial Flow Check Valve

API 6D Aixal Flow Check Valve 

Features of axial flow check valve

1. product consists of body, guide body, axial motion disc and spring parts. The product can effectively prevent the medium backflow. Ensure pipeline safety. 

2. body, disc, and tail vertebrae are designed to streamline channels with good fluid performance to minimize flow resistance and pressure. 

3. use of high performance spring materials ht/inconelx-750, with excellent corrosion resistance, oxidation resistance and excellent mechanical properties, to ensure that the spring long-term working conditions, running state. 

4. mute operation, thus eliminating noise and water hammer in valve piping to ensure equipment and piping safety. 

5. opening and closing reaction is rapid, high reliable preloading spring makes the disc rapid response to fluid pressure changes. 

6. compact structure, convenient installation, vertical, horizontal installation can be. 

7. valve adopts alloy steel surfacing sealing face, wear-resistant, corrosion-resistant, long life. 

8. valve pressure range is relatively wide.
