Tri Lok Triple Offset Butterfly Valve

Compared to gate, globe or ball valves of the same size and pressure class, Tri Lok provides space and weight savings while minimizing installation and maintenance costs. Tri Lok is a premier isolation valve, well suited for operation in light vacuum to high-pressure applications. The standard, non-rubbing, metal-to-metal sealing system is inherently fire-safe. Applications requiring absolute zero leakage are ideally suited for triple offset technology.
