Butterfly Valves
Bray - Triple Offset - Tri Lok®-Cx
High-Performance Valve for Petrochemical and Power Sectors
Tri Lok® is the premier isolation valve for operation in vacuum to high-pressure applications. The non-rubbing, metal-tometal seal delivers zero-leakage bidirectional shutoff with minimal torque, and is certified fire-tested. 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.
