King Engineering Corporation Downpipe Check Valve

This engineered component will help you prevent siphoning or backflow of liquid through a downpipe installed in tank level gauging applications. With the KING-GAGE® Downpipe Backflow Check Valve, you can guard against liquid traveling up through the downpipe and into the system pressure lines. It utilizes a specially designed float pin that rises up to seal the valve shut when liquid enters from the downpipe through the bottom of the unit. The Model 6563 Downpipe Check Valve is well suited for use on downpipe systems employing KING-GAGE Purge Control or LiquiSeal Purge Control liquid level transmitters.
