Globe center guided 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. The spring automatically closes the disc at zero flow, which prevents flow reversal and water hammer. The disc is fully guided at the top and bottom to prevent binding and cocking. The valve disc will open with less than 1/2 pound per square inch pressure. All sizes feature discs, which lift 1/3 of an inch from their seats for every 1 inch of pipe size.

Keckley globe center guided silent check valves are full bodied and provide a very low pressure drop. Keckley globe center guided silent check valves are available in cast iron, carbon steel, stainless steel, and a variety of specially cast alloys. Keckley globe silent check valves are normally stocked and available to ship immediately with metal seats. Buna-n, Viton, and EPDM seats are available and would be machined at our facility in Skokie, Illinois. The standard discs furnished in all units are stainless steel.
