AV-3A Sanitary Air Blow Check Valve (Discontinued)

Sanitary Air Blow Check Valve Applications

The Air Blow Check Valve usually works under a variety of high-pressure applications. The air pressure makes the rubber away from the seat. When air pressure is absent, the spring holds the valve closed against the seat and makes the plug back.

• Evacuation and/or drainage lines for evacuation products
• Air stirring products in pipes, storage tanks, and other equipment
• Corrosion resistance of wind lines and equipment 

Sanitary Air Blow Check Valve Description

The Air Blow Check Valve has no restriction of product because of the full unrestricted flow. The three-piece design and the removal of a minimal number of bolts allow service to be performed without the removal of the complete valve from the line.
