Clack WS1.5 Water Softener Control Valve
Engineered for serious flow and zero fuss, the Clack WS1.5 control valve is the muscle behind mid-size commercial and large residential water treatment systems.
Its rugged 1.5-inch top-mount body, offered in epoxy-coated brass or glass-filled composite, pushes up to 70 gpm of pristine water. A solid-state microprocessor gives you four regeneration triggers (meter, delayed meter, time clock, or pressure differential), 9 fully programmable cycles, and an easy front-panel readout of time, capacity, and real-time flow, plus reliable battery-backed electronics.
Built in the USA, NSF-certified, and designed around Clack’s proven stack-seal piston, the WS1.5 pairs performance with lifetime peace of mind.
