Specific features of the CVS 6000/6000A include a full waterway flow-through area and low head loss, a high-strength stainless steel shaft, a double-clevis self-aligning disc, and top entry design allowing all internal parts to be easily accessible in the field.

Available in sizes of 2 in.to 66 in. (50-1,700 mm), CVS-6000/6000A Swing Check Valves can be rated up to 640 psi CWP (4,400 kPa) and are available with ANSI Class 125/150 or Class 250/300 flanges. Closure control devices include air cushioned cylinder, oil controlled cylinder, bottom mounted buffer, lever and spring, and lever and weight. In addition, the CVS-6000/6000A may be ordered as a convertible model that allows field conversion of the closure device.

The valves are offered with Acrylonitrile-Butadiene (NBR), Terpolymer of Ethylene, Propylene, and A Diene (EPDM) or Fluoro Rubber (FKM) resilient disc seats, or cast aluminum bronze or stainless steel metal seats for durability. Body seats can be ordered with a NBR, EPDM, or FKM resilient seal.
