Bray McCannalok High Performance Butterfly Valves

Features

The Bray McCannalok High-Performance Butterfly Valve is engineered for critical industrial applications requiring zero leakage, high pressure and high temperature performance. Featuring Bray’s patented double offset disc and stem design, the McCannalok valve minimises torque, reduces seat wear, and extends service life beyond 100,000 cycles under extreme pressure. The McCannalok valve delivers bi-directional zero-leakage sealing in severe media, corrosive chemicals, seawater and high-temperature gases.

 

Available in wafer, lug, and double-flanged body styles, the McCannalok combines precision engineering, rugged reliability and simplified field maintenance, making it the trusted solution for global industries seeking safety, efficiency, and long-term performance.
