Features: (metal) meets or exceeds API 598 test requirements. resilient seats (Viton/Buna) ensure a bubble tight seal.

• Low weight and short laying length produce savings in initial cost, space requirements, and installation when compared to full-body, swing-type check valves.

• Contour of body provides a short and straight flow path that generates very little turbulence. Additionally, the spring-loaded discs are designed with very low cracking pressure which reduces the amount of energy required to open the valve.

• 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 to keep slamming and surges to a minimum.

• The spring and discs are designed to allow the discs to lift linearly before pivoting to avoid the disc heal from scrubbing the sealing surface. Also, discs are equipped with cast-in shock bumpers that help to reduce wear and tear on internal components.

• The retainer-less body design eliminates potential leak paths to the environment so there are no body emissions.

• Board, lapped sealing surface
