Reliable Air Release for Slurry Applications

Long-Lasting and Maintenance-Free

Bray’s SlurryTuff™ brand includes the EZI-VAC line of air release and vacuum break valves. Available in single-acting, double-acting, and triple-acting models, the valves are designed to discharge or introduce large amounts of air from pipelines while being filled or drained.

Bray EZI-VAC valves are designed for the most arduous applications including mining slurries and and mine dewatering which cause conventional air release valves to fail.  EZI-VAC valves provide critical protection against choked flow, head loss, vacuum collapse, water hammer and pump damage.
