- Flanged Ends.
- Globe Type.
- 2 Inch Check Valve.
- Body: Ductile Iron A536.
Designed for Long Service Life:
Newly designed CV50's have straightening vanes that reduce turbulence in incoming flow, thus minimizing noise, vibrations, errosion, cavitations and other factors that could result in premature valve failure.
Minimal Head Loss:
Head loss is minimized by the integral straightening vanves that help create laminar flow. A large cross-sectional area also lessens pressure drop across the check valve. Unlike typical conical spring construction that restricts flow, the new CV50 has a compression spring coupled with a small stem guide that allows for an unobstructed flow path.
Quick Closure to Reduce Water Hammer:
Shut-off is achieved via the fully automatic, spring-assisted disc that close near zero flow velocity. The lightweight, split disc design creates a positive shuoff prior to flow reversal and helps to kep slamming and surges to a minimum.
Ductile Iron Body:
Ductile iron body maintains the anti-corrosive properties of cast iron while achieving a yield strength comparable to carbon steel. Ductile iron also offers high pressure/temperature ratings than cast iron.
Resilient Soft Seats:
Resilient soft seats (EPDM, Viton or Buna) ensure a bubble tight seal that meets or exceeds API 598 test requirements.
