Clack WS3 Water Softener Control Valve
Meet the muscle behind commercial water treatment: the Clack WS3 control valve.
Its 3-inch, epoxy-coated brass body unleashes 250 gpm service flow and 220 gpm backwash, dwarfing valves while shrugging off corrosive environments.
A solid-state brain offers 9 fully programmable cycles, 4 regeneration triggers, and network control of up to 16 valves through Modbus or simple Cat5 cabling.
The blue back-lit screen delivers real-time flow, capacity, and diagnostic history, guarded by capacitor backup.
Tool-free piston access, an expanding-seal spacer stack, and NSF 44/61/372 listings make WS3 the bulletproof heart for high-capacity softeners or filters in municipal and industrial plants worldwide.
