V-TEK™ Hygienic Air Blow Check Valve

Filtered air enters the adapter (A) and exerts pressure on the valve plug assembly (B), causing it to move forward and unseat. The filtered air passes through the valve and around the valve plug assembly (B), entering the pipeline or tank.

When the air pressure entering the adapter (A) is shut off, the valve plug assembly is returned to its normally closed position by return spring, preventing any product or CIP solution back flow.

Main Applications:

• HSS Air Blow Check Valves are designed to evacuate lines of product or CIP solutions.
• Fail Safe Operation – backflow of product or CIP solution prevented by simple air to open, spring to close operation.
• Also used for air agitation of product in tanks and other vessels.

It is recommended to use the air blow check valve to evacuate the lines of product or CIP solution and to clamp it on the end of the “Y” branch of our ball check valve, rather than install it in the line.
