1. The product is composed of valve body, flow guide body, axial movement valve disc and spring component. Products can effectively prevent the media from backstreaming. Ensure pipeline safety.

2. The valve body, disc and tailbone are designed to be streamlined passages with good fluid performance to minimize flow resistance and pressure.

3. The use of high-performance spring material HT/INCONELX-750, with excellent corrosion resistance, oxidation resistance and excellent mechanical properties, to ensure long-term operation of the spring under the conditions of operation.

4. Mute operation, thereby eliminating noise and water hammer in valve piping to ensure safety of equipment and piping.

5. Opening and closing react quickly, high reliable preloading spring makes the disc respond to the change of fluid pressure quickly.

6. Compact structure, convenient installation, vertical and horizontal installation.

7. The valve is made of alloy steel overlaying welding cover, wear-resistant, corrosion resistant and long life.
