Wheatley Piston-Style

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.
