The Runxin F71B1 (Model 53502) is an automatic multiport filter control valve engineered for small to medium water treatment systems such as sand filters and activated carbon filters. Designed for durability and precision, this top-mounted valve automatically performs Service, Backwash, and Fast Rinse operations through a programmable time clock or meter-based control system.

Its corrosion-resistant construction and reliable sealing make it ideal for both domestic and light commercial use. The valve also features manual override, a digital LED display, and an interlock function that prevents multiple valves from rinsing simultaneously in multi-tank systems.
