F112A Automatic Multiport Softener Valves The F112A automatic multiport softener valve features a flow rate of 40m³/h. The F112A3 comes with 4 ports in a T-configuration within the valve body. Unfiltered water is brought in from the pump port, which is sent to different passages for treatment. The different flow passages are easily controlled through pushing or pulling the hydraulically balanced pistons in the valve. Also, the F112A3 is equipped with a booster pump which makes it possible to ensure normal piston operation when the inlet pressure is under 0.2MPa. This device can be used in boiler softening systems and softening in RO pretreatment.
