DeZurik’s APCO CVS-60000/6000A Swing Check Valves are developed for clean and dirty services – including water, sewage or industrial applications. These heavy-duty valves are designed to handle higher flow rates and pressures and to withstand shock.
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 2-66″ (50-1700mm), CVS-6000/6000A Swing Check Valves can be rated up to 640 psi CWP (4400 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 & spring, and lever & weight.
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.
