Globe Silent Check Valve
APPLICATIONS
Liquid or gas where protection from flow reversal in a pipeline is required.
CONSTRUCTION
The Keckley Style CG Globe Silent Check Valves are constructed from rugged castings that are machined to exacting specifications. Their bodies have drilled flanges that are in accordance with ASME. Reference individual technical data pages for standard disc, seat, guide pins, and bushings.
FEATURES
  • A spring automatically closes the disc at zero flow, which prevents flow reversal and water hammer.
  • The seat and disc’s mating surfaces are hand lapped.
  • The disc is fully guided at the top and bottom to prevent binding and cocking.
  • Designed for a minimum open area equal to 110% of the pipe size.
  • All sizes feature discs, which lift 1/3 of an inch from their seats for every 1" of pipe size.
  • The disc will open with less than a 1/2 pound per square inch pressure.
  • Epoxy coating is standard.
  • Optional soft seat provides bubble tight shut off.
  • Field serviceable without the need for special tools.
INSTALLATION
The Style CG is used in both vertical and horizontal applications. Contact Keckley for downward vertical flow installations.
