Features & Benefits

The Bray/McCannalok Series 41R high performance butterfly valve is specially designed for the sugar industry to offer rugged reliability and extremely easy maintenance in the field. Independent and internal tests have proven Bray/ McCannalok’s superior service life capability, with zero leakage shutoff through over 100,000 cycles.

This valve incorporates the same proven design features of the standard Bray/McCannalok butterfly valve, which has proven to be the leader in double offset valve design for over 30 years, in a lighter and more economical configuration specifically designed to handle the low pressure steam of evaporators. It can be used along with the standard higher pressure Bray/ McCannalok butterfly valves and shares the same spare parts, thereby reducing the need for special or different inventory.

The Bray/McCannalok’s unique, patented design received Chemical Processing’s Vaaler Award for Best Product shortly after it was introduced. The Bray/McCannalok valves can be easily automated with manual, pneumatic or electric actuators.
