The portfolio of WKM valves includes triple-offset valves (TOVs) that incorporate true triple-offset geometry to provide bubble-tight sealing. The result is the fully bidirectional zero-leakage shutoff valve that sets the benchmark for reliable, repeatable isolation performance. 

Rigorous testing and advanced engineering

As a member of the proven Cameron quarter-turn butterfly valve portfolio, each WKM TOV undergoes arduous qualification and testing processes that simulate the valve life cycle. Every TOV is designed and built with the manufacturing excellence and commitment that distinguish all Cameron product lines.

Worldwide footprint and support

Our global support and strategic networks brings the WKM TOV where and when it is needed—fully designed, tested, qualified, and backed by Cameron, the leader in valves manufacturing.
