Vacuum Breaker Valve Freshwater Ref: 33VB

Designed to protect pipelines from vacuum collapse in fire protection systems, the Cla-Val Model 33VB Vacuum Breaker Valve prevents vacuum conditions from forming at high points in the pipeline. The valve’s large intake orifice freely admits air during pipeline draining.

The valve’s many benefits include the following:

•  Fully unrestricted vacuum protection

•  400 psi maximum operating pressure

• Resilient seat included for drip-tight closure

• Large valve orifice allows for air intake at 1/4 psi vacuum

• Standard epoxy coated ductile iron body

• Easily serviced without removal from pipeline
