Product Description

The silent check valves with a cast iron body, use a fully automatic spring assisted discs to eliminate water hammer while preventing flow reversal in the piping. The spring closure acts faster than that swing check valves, which can slam shut with the flow reversal.

The wafer type body design is compact, versatile, and fits inside of the bolting in a flanged connection. For 2″ to 10″ diameters, the 125# wafer design allows for mating to either 125# or 250# flanges. For 8″ to 10″ diameters, a 250# wafer design is also available for mating to 250# flanges. Also available with grooved end adapters.

  • It is recommended that valves be installed 7 to 10 pipe lengths away from the turbulence.
  • *12” size has special full lug pattern.
  • Consult factory for optional construction materials and installation instructions. Optional resilient seating of NBR or EPDM available for 6” size and larger.

Note: Manufacturer reserves the right to modify dimensions, materials, or design. Consult factory for certification.
