Features & Benefits

High Pressure, High Temperature, Zero Leakage Butterfly Valves

The McCannalok high performance butterfly valve (also known as a double offset butterfly valve) features an innovative design that offers rugged reliability and extremely easy maintenance in the field. Independent and internal tests prove the Series McCannalok valve's superior service life capability, with zero leakage shutoff.

The McCannalok valve’s unique, patented design received Chemical Processing’s Vaaler Award for Best Product shortly after it was introduced. The simple, innovative design offers rugged reliability and extremely easy maintenance in the field.

Independent and internal tests have proven superior service life capability with zero leakage shutoff through over 100,000 cycles. Series 40 Bray/McCannalok valves can be automated inexpensively with any of Bray’s pneumatic and electric actuators. The McCannalok high performance valve delivers the highest quality and highest value available for your requirements. After a test of over 100,000 cycles at 720 psi (49.6 Bar), the seat remained in excellent condition, continuing to provide a bi-directional zero leakage seal. Even after more than 878,000 cycles at 2 psi (0.1 Bar), the McCannalok high performance valve still sealed zero leakage in both directions.
