ASCO 304-354 Rebuild Kit

The ASCO 304-354 Rebuild Kit is an essential maintenance solution for servicing ASCO 2-way solenoid valves, specifically optimized for the 8210 series. This kit facilitates a complete internal overhaul, addressing common failure points such as worn NBR diaphragms and degraded solenoid seals. Engineering for high-cycle industrial applications, the components within this genuine ASCO spare part kit ensure optimal pressure ratings and flow coefficients (Cv) are maintained. By replacing the solenoid core assembly and internal gaskets, technicians can eliminate internal leakage and prevent coil burnout caused by mechanical resistance. This kit is designed for water, air, and light oil applications where maintaining a tight shut-off is critical for system safety and efficiency. Integrating these HVAC replacement parts into a preventative maintenance schedule reduces unplanned downtime and extends the service life of existing valve bodies without necessitating a full valve replacement.

• Restores solenoid valve performance to original factory specifications.
• High-grade Buna-N (NBR) components provide excellent chemical resistance for standard media.
• Reduces operational noise by replacing worn solenoid springs and plungers.
• Cost-effective alternative to complete ASCO valve replacement.
• Ensures compatibility with Normally Closed (NC) configurations in the 8210 series.

What is included in the ASCO 304-354 Rebuild Kit?
The kit typically includes a new diaphragm, core assembly, core spring, and all necessary O-rings and gaskets required for a standard internal rebuild.

Will this kit work for high-temperature steam applications?
No, this kit utilizes NBR seals. For high-temperature steam, you must source a kit with EPDM or FKM (Viton) seals specifically rated for those thermodynamic properties.

How do I know if my 8210 valve needs a rebuild?
Common indicators include intermittent sticking, audible buzzing from the coil, or fluid bypassing the seat while the valve is in the de-energized position.
