7500-Rev21 Commercial Up-Flow Softener Control Valve 2” (F99D3)

Description

7500-Rev21 (Runxin RevV21 F99D3) 2" Commercial Up-Flow Softener Control Valve

A heavy-duty 2" digital control valve for commercial water softeners with up-flow (counter-current) regeneration. Up-flow regeneration refills the brine tank with softened water and uses brine efficiently, making it a good fit for boiler feed, RO pretreatment and other commercial softening systems.

Note: this valve is for water softeners only. For iron, carbon or sediment filters, use our 2" commercial filter valve.

Key Features

• Up-flow regeneration: brine refill uses softened water.
• Flow meter (meter-controlled): four meter modes: delayed, immediate, and "intelligent" delayed or immediate (calculates capacity from resin volume and hardness). Also regenerates after a set maximum number of days.
• Electronic brine refill: a motorized ball valve controls brine refill during service, shortening the regeneration cycle.
• No hard water bypass during regeneration (single-tank systems).
• Ceramic disc seals for reliable sealing and corrosion resistance.
• Multi-tank ready: interlock (only one valve regenerates at a time), signal output, remote start input and pressure-relief output for booster pump systems.
• Power outage memory: settings are kept; the time of day flashes after a long outage.
• Keypad lock and LED display.
• Top or side mount with the side-mounted connector.
