Motorized Alternating Valve Installation Guide For EE & EL

The Clack Motorized Alternating Valve (MAV) for EE and EL systems allows for twin-tank configurations to provide uninterrupted treated water and is controlled by the control valve's circuit board.

Twin Alternating Systems: Enables two control valves ( WS1.25, WS1.5, WS2, WS3) to work in an alternating system, ensuring a continuous supply of treated water.
No Raw Water Bypass: Prevents untreated water from entering the service line during a regeneration cycle.
Low Pressure Loss: Designed with full ports ( 1.25″, 1.5″, 2″, or 3″ depending on the model) to minimize pressure loss.
Durable Construction: Features an epoxy-coated lead-free brass valve body or high-strength composite materials for corrosion resistance.
Automated Control: Uses a reliable low-voltage DC drive assembly that is fully controlled and powered by the control valve’s circuit board, requiring no separate power source.
Flexible Regeneration Source: Provides the option for regeneration using treated or untreated water sources.
