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

Typical Applications:

•  Standard Max. D.W.P. 300 psi (for higher operating pressures, consult factory)

•  Transmission pipeline high points

•  Water treatment plant piping high points

•  Offshore platforms

•  Vertical turbine pump discharge
