RUNXIN F74B1
RUNXIN F74B1
The F74B1 automatic multiport softener valve features a flow rate of 10 m³/h and uses a planar, corrosion-resistant gasket for opening and closing. Backwash, brine, and slow rinse, brine refill, and fast rinse functions can be realized by this valve.

Primary Applications
The F74B1 is suitable for a variety of water treatment scenarios, including:
- Household softening systems for residential use.
- Ion exchange equipment for industrial and commercial applications.
- Boiler feed water softening systems to prevent scaling.
- Reverse Osmosis (RO) pretreatment softening systems.
Operation Cycles
- Service: Normal operation, producing treated water.
- Backwash: Water flows upward to lift and clean the resin bed.
- Brine & Slow Rinse: Salt solution is drawn from the brine tank to regenerate the resin.
- Brine Refill: Fresh water is added to the brine tank to prepare a salt solution for the next regeneration.
- Fast Rinse: A final high-speed rinse to remove any remaining brine and prepare the system for service.
Key Features
- Regeneration Control: The valve can be configured as either a Time Clock type (regenerates after a set number of days/hours) or a Meter type (regenerates based on water usage). The control board allows you to switch between these types.
- No Raw Water Bypass: During regeneration, the valve automatically blocks the outlet, ensuring that untreated water does not enter the downstream system.
- Manual Function: Allows you to initiate regeneration immediately with the press of a button.
- Interlock Function: In systems with multiple tanks, this function ensures that only one valve regenerates at a time while the others remain in service.
- Signal Output: The valve has a connector for external wiring, such as controlling a booster pump or an upstream water pump.
- Long Outage Indicator: If power is lost for more than 3 days, the display flashes to remind the user to reset the time of day, but the programmed parameters are retained.
Installation Types
The F74B1 is a single-tank control valve that does not provide treated water during the regeneration cycle. It is shipped as a top-mounted valve (installed on top of the tank), but it can be converted to a side-mounted configuration using an adapter, allowing for more flexible space management.
