AMERICAN Flow Control's Series CV 2200 Swing Check Valves are in full compliance with ANSI/AWWA C508 with a rated working pressure of 350 psig.
The check valve body and bonnet are constructed of ductile iron and coated with fusion-bonded epoxy inside and outside.
The disc is constructed of bronze and is available in either resilient or metal seated configurations. The resilient seated disc is equipped with a rubber seal to provide closure, even at low pressure.
The disc and arm assembly are attached to the bonnet for ease of removal. Removing the bonnet will remove the disc and arm assembly from the check valve.
The shaft is constructed of Type 316 stainless steel. In addition to the standard inside shaft configuration, an external shaft is also available for the use of a weight or spring assist for applications where rapid flow reversals may be encountered. The external shaft may be configurated to exit either or both sides of the valve.
The shaft is held in place by corrosion resistant bronze shaft supports. These supports also act as wear-resistant bearings and are easily removed for disassembly of internal parts.
These check valves have a “Clear Waterway” per MSS SP-136. Swing check valves with a Clear Waterway, when fully open, have an unobstructed cylindrical flow path through the valve.
