Here is how it works :

When the Air Op Dilution Drain valve's air pilot is actuated, a unique dual acting piston opens both the Drain port and the Fresh water port thereby draining the tank while cooling  and diluting the process via the ultimate drain port simutaneously.

As the pilot de_activates the drain port and fresh water port close when the valve piston returns to the closed position.


DILUTION RATIOS:


Dilution Ratios are provided by a Teflon disc with a predetermined thru hole provides the exact ratio. The disc is installed in the Drain port at the factory and ready to hook up. No disc will give you 2:1 Ratio. Specify Dilution Ratio when ordering.
