Features:

  • Designed for long service life
    Newly designed CV51's have straightening vanes that reduce turbulence in incoming flow, thus minimizing noise, vibrations, erosion, cavitations, and other factors that could result in premature valve failure.

  • Minimal head loss
    Head loss is minimized by the integral straightening vanes that help create laminar flow. A large cross-sectional area also lessens pressure drop across the check valve. Unlike typical conical spring constructions that restrict flow, the new CV51 has a compression spring coupled with a small stem guide that allows for an unobstructed flow path.

  • Quick closure to reduce water hammer
    Silent shut-off is achieved via the fully automatic, spring assisted disc that closes near zero flow velocity. The lightweight, center guided disc design creates a positive shutoff prior to flow reversal and helps to keep slamming and surges to a minimum. Additionally, the low cracking pressure of the CV51 reduces the amount of energy required to open the valve.

  • Metal-to-metal seats
    Precision machined sealing surfaces allow the CV51 to maintain a tight seal that meets or exceeds API 598 leakage requirements. Resilient seats are also available to provide bubble tight seals. Sealing is further improved by an additional gasket assembled with the seat independent of the flange gasket.

  • Versatile design
    Clearance within the CV51's body allows a butterfly valve to be installed directly on the outlet side of the valve without extra piping. Because the valve's trim is interchangeable, various seats, discs, and springs are available and easy to replace. Exotic spring material, such as Monel or Inconel 750-x, can easily be substituted for the standard stainless steel.
