F77AS Manual Multiport Softener Control Valves Featuring a flow rate of 15m³/h, the F77AS manual multiport softener control valve is equipped with two valve cores, one controlling the inflow of the water, the other responsible for outflow. The different functions such as service, backwash, brine and slow rinse, brine refill and fast rinse can be realized through rotating the handwheel counterclockwise to put the two pointers in the desired precision. Product Characteristics Simple structure and reliable sealing It adopts hermetic head faces with high degree pottery and corrosion resistance for opening and closing. It has two valve cores. One controls inlet water, the other controls outlet water. No water pass the valve in regeneration in single tank type. Brine refill controlled by manual ball valve. （F77AS/61215，F77CS/91215） During service, manual ball valve will control to start the brine refill, in order to shorten the regeneration cycle time. Two ways for installation Use side-mounted connector to change the valve from top-mounted to side-mounted. F77CS can be installed in top mounted or side mounted. (When side-mounted connector TOP side connected with top strainer, BOTTOM side connected with side bottom strainer) It’s up-flow for regeneration. If connector with side-mounted in upside down (TOP side connector with bottom strainer, BOTTOM side connected with top strainer) It’s for floating bed system. For filtration system Drain outlet is the same size as water outlet. Block the brine line connector change the valve to F77BS filter valve.
