ASCO 302-270 Rebuild Kit

The ASCO 302-270 Rebuild Kit is a comprehensive maintenance solution engineered for the high-cycle demands of ASCO 8210 Series solenoid valves and compatible 8210B020AC and 110/50D models. Designed for professional solenoid valve repair, this kit resolves common failure points such as internal leakage and sluggish actuation by refreshing the entire internal valve pilot and diaphragm assembly. This factory-spec kit includes a precision-machined core assembly, a durable core tube assembly, a high-performance diaphragm, a replacement bonnet, seat, and tension-calibrated springs. By replacing these critical wear components, technicians can restore original flow characteristics and pressure ratings without the expense of full valve replacement. Whether you are dealing with a ASCO 8210B020 in a commercial HVAC system or industrial process control, the ASCO 302270 kit provides the exact tolerances required for leak-tight seating and reliable 2-way normally closed operation. Each kit comes with technical instructions to ensure correct alignment and torque during reassembly.

• Restores Seal Integrity: Includes a new diaphragm and seat to eliminate internal bypass and external leaks.
• OEM Compatibility: Specifically engineered for ASCO 8210 Series valves, ensuring exact drop-in fitment.
• Prevents Coil Burnout: Replacing a binding core assembly reduces inductive heat and protects the solenoid coil.
• Full Component Refresh: Provides all high-wear parts, including the core tube and springs, for a complete overhaul.

Which valve models are compatible with the ASCO 302-270 kit?
This rebuild kit is primary designed for the ASCO 8210 series, specifically models 8210B020AC, 8210B021, and 110/50D. It is often cross-referenced with Grainger numbers 3UK18 and 3UK19.

Does this kit include the solenoid coil?
No, this is a mechanical rebuild kit. If your valve is failing to energize due to an electrical fault, you may need a separate ASCO replacement coil.

Can I use this kit for high-temperature or steam applications?
This kit is built to standard specifications for the 8210 series. Always verify the elastomer material (typically NBR or EPDM) against your specific media and temperature requirements before installation.
