33A

High-Performance Air Release & Vacuum Breaker Valve

Designed to protect pipelines and vertical turbine pump applications from air lock and vacuum collapse, the Cla-Val Model 33A High-Performance Combination Air Release & Vacuum Breaker Valve eliminates air and prevents vacuum formations in waterworks piping systems. A large venting orifice and large float clearances freely exhaust or admit air during pipeline filling or draining.
