Automatic Shut-Off Valve, 4 Way 1/4 JACO

The dual diaphragm design of FLOWMATICS's WQA validated valves provide automatic shut-off to supply line when storage tank reaches 65% of inlet pressure, saving thousands of gallons of water per year. Valves are made using FDA grade and NSF certified materials.  Available in Black or White , we reserve the right to substitute colors.Here's how it works: The valve automatically shuts off production when the tank pressure reaches approximately 65% of the incoming line pressure to indicate the tank is full. This device saves thousands of gallons of water. RO Systems without an ASO valve continually send Rinse water to the drain even when the tank is full. Installation:Insert the tube feeding the membrane inlet into the ASO IN/OUT fittings: Insert the tube from the PREFILTER Outlet into the IN fitting . Insert the opposite tube end that feeds the Membrane INLET into the OUT fitting . NOTE: The IN & OUT markings are on the screw side of the valve - THIS IS THE HIGH PRESSURE FEED SIDE. Insert the tube feeding the tank from the Product Water port of the membrane housing: Locate the Product Water outlet from the membrane housing . Insert the Product water tube from the membrane housing into either Tank fitting of the valve . Insert the opposite tube end that feeds the Tank into the other Tank fitting of the valve.
