Fully automatic HF-DBV (high flow drain back valve)

This new valve was created for irrigation/sprinkler lines that need to drain out completely so they don’t freeze.  During sever cold weather it is necessary to drain distribution lines as fast as possible to eliminate freezing of components that could possibly be damaged.  The new valve does a great job of allowing drain back to the tank once the pump cycle is completed.  The current valve works well with high flow pumps (submersible) with flow rates in excess of 10 gallons and a static head in the 150-250 feet range
