Toro P220-26-98 2" NPT Electric P-220 Scrubber Series Valve with DC Latching Solenoid. True dirty water irrigation valves, the Toro P-220S Scrubber Series valves are built to handle chlorine, chloramine, and other chemicals found in reclaimed and non-potable water systems. Constructed of heavy duty, glass-filled nylon and EPDM rubber components the P-220S valves feature Toro’s patent-pending Active Cleansing Technology (ACT™), which helps prevent the build-up of sand, algae, and other organic materials that may inhibit water from metering properly through the valve.
