Tom Wheatley Piston-Style Check Valve

Because of its unique nonslam design, the piston-style TOM WHEATLEY check valve has provided years of uninterrupted service downstream from reciprocating pumps and compressors, and in other applications where conventional check valve designs would be subjected to excessive wear. 

The valve's top-entry design allows for easy access and replacement of all valve internal parts with reduced downtime.

Tom Wheatley Swing-Style Check Valve

The swing-style TOM WHEATLEY check valve is used in critical service applications worldwide. The swing check design prevents backflow in a fraction of a second and there is no need for expensive actuation.

The swing-design TOM WHEATLEY check valve is also available for subsea application. This model features a unique, free-swinging clapper. If a reverse flow or critical pigging operation is required, the clapper can be manually, ROV, or hydraulically actuated and held in a full open position.
