Server Room Valve for Cooling System Make up Water and Humidity Control

Single-tank automatic softener valve
A. Down-flow regeneration softener valve
Down flow regeneration softener valve refers to control valves where the direction of the brine
flow is the same as the service water flow, which is from top to bottom. The regeneration process
typically includes service to invalid → backwash → brine & slow rinse → brine refill → fast rinse
→ service to provide softened water. During the regeneration process, when the brine flows from the
top to the bottom of the resin tank to the protective layer of resin, the brine, after the exchange
reaction, not only has a very low concentration of Na+, but also contains a large amount of
exchanged Ca2+ and Mg2+. Therefore, it is necessary to increase the amount of salt used to ensure the
regeneration of the bottom layer of resin, which results in higher salt consumption. However, the
down-flow regeneration process is simple and easy to control, that is why down-flow regeneration
softener valves are the most widely used. We offer the most models in this type of control valve,
including the F63, F65, N74, N77A, F95A, F112A, F96A, F147A, and others. Their specifications
and dimensions can be found in Table.
