The surface form a protective film after Hare face treatment for trim. It not only improves anti-corrosion performance, but also can open and close easily because of improved surface hardness.

Main Part Material
Titanium Gr2, Gr3, Gr5, Gr6, Gr7, Gr12
Titanium GrC2, GrC3, GrC5, GrC6, Ti-Pd7B, GrC12
Titanium GrF2, GrF3, GrF5, GrF6, GrF7, GrF12

Technical Feature
1. Stopper pins avoid the over travel of a disc.
2. Resilient or Metal Seats resilient seats in EPDM, NBR or FKM ensure a bubble tight seal that meets or exceeds API 598 test requirements. Lapped metal seats meet or exceed API 598 test requirements.
3. Eyebolt hook design upon size≥4", easy for on-site installation.
4. Spring loaded on discs assist valve closing to ensure tight seal and Minimize Slamming, to keep the valve performance reliable. ≤6”, Uni Spring; >6", double spring or more.
5. Cost Efficient Design: The low weight and short laying length saves initial cost, requires less space, and is easier sealing to install when compared to full-body, swing-type check valves.
6. Quick Close to Reduce Water Hammer Shut-off is achieved via the fully automatic, spring assisted discs that close near zero flow velocity. The lightweight, split disc design creates a positive shutoff prior to flow reversal and helps minimize valve slam and surge.
