Introduction
The 2400VS is an electronic 4-cycle regeneration control valve for softening of drinking and feed water supplies.
The unique motor driven rotor assembly has a minimum of moving parts; together with the 1-piece Noryl® body,
this guarantees extremely high flow rates and exceptional reliability. The microprocessor controlled programmer
with NOVRAM®, offers unrivalled programming simplicity for use in demand with days override systems. The
control valve is designed for hard water bypass during regeneration. A built in adjustable blending device for
mixing hard and soft water to suit the particular needs of each installation, is a standard feature. The control valve
requires only an aircheck; a conventional float-controlled brine valve system can be used as a double security. The
following sequence is followed:
1. SERVICE:
Untreated water flows down through the resin bed and up through the riser tube; the water is conditioned when
passing through the resin. The throughput is dependent on the maximum permissible pressure drop for the
complete water softener and the maximum permissible specific load of the resin (generally taken as 40 litres
soft water per hour per litre resin).
2. BACKWASH:
Water flows down through the riser tube and up through the resin bed to drain; the resin bed is fully expanded
and all foreign materials are thoroughly washed from the resin, allowing a good brine cycle to occur.
3. BRINE:
Salt brine, drawn from the brine tank by the injector, slowly flows down through the resin bed and up through
the riser tube to drain; the resin is being regenerated when the salt brine passes through. The brine cycle is
terminated when the air check is shut.
4. SLOW RINSE:
Slow rinse continues for the remainder of the brine cycle; the injectors motive water slowly flows down through
the resin bed and up through the riser tube to drain, slowly washing the brine from the resin tank.
5. FAST RINSE/BRINE REFILL:
Water flows to the brine tank and at the same time down through the resin bed and up through the riser tube to
drain, ensuring that all traces of brine are washed out and that the resin bed is compacted. The resin bed is now
ready for the next service cycle.
