ASCO 302925-MS Valve Repair Kit

The ASCO 302925-MS Valve Repair Kit is a factory-original rebuild set for ASCO Red Hat solenoid valves, designed to restore operation to Emerson ASCO 220/50D family units. It includes a complete array of internal components—Cap Retaining, Clip Retaining, Core Assembly, Cup, Holder Assembly, M Insert, O-Rings, Piston Assembly, Screw Mach RH, Solenoid Base Sub-Assembly, Spring Compression, and U-Rings—precisely the parts needed for a full valve rebuild. The kit is specified for use with ASCO/Emerson valve models such as 220/50D and EF8321G001AC240/60 and is UL-listed, meeting standard electrical safety requirements. By replacing worn components rather than the entire valve, it provides a cost-effective maintenance option for HVAC and hydronic systems that rely on ASCO Red Hat valves.
