Willoughby 980305 Water Diaphragm PVK-3 Repair Kit

Product Description

The WILLOUGHBY 980305 is a water diaphragm repair kit designed for the PVK-3 valve assembly. This kit provides the replacement diaphragm and associated components needed to restore proper flow control to a worn or failed valve. Diaphragm valves regulate water flow by flexing an internal membrane against a seat, and when that membrane degrades, leaks or loss of pressure control follow. The 980305 kit addresses that failure point directly, allowing a plumber or facility maintenance technician to rebuild the existing valve body rather than replace the entire assembly.

This repair kit is suited for use in commercial and institutional plumbing systems where PVK-3 diaphragm valves are installed. Typical applications include restrooms, washdown stations, and water control fixtures found in schools, correctional facilities, healthcare buildings, and similar high-use environments where WILLOUGHBY fixtures are commonly specified. The kit is intended for in-field service by licensed plumbers or qualified maintenance personnel.
