Tom Wheatley
Piston Check

Overview

Thanks to a unique non-slam design, the Cameron TOM WHEATLEY piston 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 easy access and replacement of all internal parts with reduced downtime.

Standard Features

• Size range: 2" through 12" (50 mm through 300 mm)
• ANSI Classes: 150 to 1500
• Full-open / top-mounted
• Controlled clapper movement
• Horizontal or vertical service
• Metal-to-metal seats
• Quick opening of piston
• RF or RTJ end connections

Optional Features

• Integral or removable seat
• Metal overlays

Body Construction

Carbon steel body, cover, and trim.

Applications & Benefits

The non-slam piston design and controlled clapper movement prevent the water-hammer and wear that damage conventional checks downstream of reciprocating pumps and compressors, extending service life in pulsating flow. Top-entry access means all internals can be serviced in line with minimal downtime, while metal-to-metal seats and a wide ANSI Class 150 to 1500 range in sizes 2" through 12" support high-pressure horizontal or vertical installations with RF or RTJ connections.
