This Toro P220S-Kit-04 scrubber valve diaphragm assembly is constructed of EPDM rubber that has been reinforced with fabric so the diaphragm and seat will work in practically all water applications. The Toro P220S Scrubber Series of irrigation valves are designed to utilize reclaimed and non-potable water that contains such chemicals as chlorine, chloramine, and others. This Toro P220S-Kit-04 is for 1-inch NPT inlets/outlets and is the replacement diaphragm assembly kit for Toro P220S scrubber valves. Toro's patented Active Cleansing Technology (ACT) continuously cleans the valve to help prevent sand as well as algae and other organic matter from building up and inhibiting the properly-metered flow of water.
