|62-174/326 Air Blow Check Valve|
|62-174 and 62-326 Air Blow Check Valves |
Alfa Laval®’s Tri-Clover® brand Air Blow Check Valve is designed to (1) evacuate lines of product or CIP solution and (2) for air agitation of product in tanks and other vessels. It also helps to protect pipelines against corrosion – air drying of lines permits formation of protective oxide film . . . the key to placing a system in its most corrosion resistant condition. Improves product uniformity and quality – product air agitation thoroughly mixes and blends product.
- - Fail Safe Operation – backflow of product or CIP solution prevented by simple air to open, spring to close operation.
- - Easy Assembly/Disassembly – Tri-Clamp® connections permit quick disassembly and assembly for replacing Filter Media, cleaning or inspection.
- - Remotely Controlled – can be remotely controlled by controlling the supply of air to the valve.
- - Rugged Construction – type 316 stainless steel is standard. Spherical plug assembly is bonded EPDM rubber.
- - Conforms to 3A Accepted Practices – for applications requiring a final filtering of air prior to entering tank or pipelines.
Filtered air enters 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 backflow. The Air Blow Check Valve can be used in any position, horizontal or vertical.
The Air Blow Check Valve is easily installed on tanks or other vessels, for product agitation, by using a Tri-Clamp, a gasket, and a mounting ferrule. No other fittings are required. To use the Air Blow Check valve to evacuate lines of product or CIP solution it is recommended that it be clamped on the end of the “Y” branch of a Ball Check Valve then installed in the line. See page 3 for illustrations of typical installations.
