The Fulaik 2850 softened water control valve is a fully automatic water softener for groundwater well water softening. It belongs to a single piston industrial control valve, with a single piston arranged horizontally, suitable for single valve and single tank systems, and can be equipped with additional valves for dual valve and dual tank systems.
Working principle of fully automatic water softener:
When the raw water containing hardness ions passes through the resin layer of the exchanger, the calcium and magnesium ions in the water are replaced by the sodium ions in the resin. The resin adsorbs the calcium and magnesium ions, and the sodium ions enter the water. In this way, the water flowing out of the exchanger is softened water without hardness ions. As the exchange process continues, all Na+in the resin is replaced to saturation and loses its exchange function. At this point, an industrial NaCl (carbon free) solution must be used to regenerate the resin, replacing the Ca2+and Mg2+adsorbed by the resin. The resin then re adsorbs sodium ions and restores its softening exchange capacity.

Features of fully automatic water softener equipment:
1. High degree of automation and stable operating conditions.
2. Advanced program control device, accurate and reliable operation, replaces manual operation, and fully realizes automatic conversion of various links in water treatment.
3. High efficiency, low energy consumption, and economical operating costs. Due to the reasonable overall design of the softener, the exchange capacity of the resin can be fully utilized. The equipment adopts a jet type salt suction instead of a salt pump, reducing energy consumption.
4. The equipment has a compact structure, occupies a small area, saves infrastructure investment, is easy to install and debug, is easy to use, and has stable performance of operating components.
Work procedure:
1. Water supply: Untreated water passes through the resin layer, undergoes an exchange reaction, and produces soft water.
2. Backwash: Water enters from the lower part of the resin layer, loosens the resin, and removes fine impurities.
3. Salt water regeneration: Using high concentration salt water (NaCl) to flow through the resin, the failed resin is restored to sodium type usable resin.
4. Rinse: According to the process of water supply, rinse excess salt solution and regenerated calcium and magnesium ions through resin.
5. Water injection: Inject water into the salt tank to dissolve the salt for the next regeneration.
