Pentair In Line Chlorinator 320 Control Valve | R172086

The Pentair R172086 control valve serves as a direct replacement for the Rainbow 320 and 322 in-line feeder systems and select models in the 300-series off-line lineup. Designed with a ½-inch FPT connection, the valve meters water into the feeder body to regulate chlorine or bromine release, helping maintain stable sanitizer levels. Its material composition is resistant to chemical exposure and crafted to align with the original OEM performance standards used in Pentair’s Rainbow feeder line. When aging or obstructed valves impact feed rate consistency, installing the R172086 restores proper operation and supports dependable sanitization for residential and commercial pools.
