ASCO 323-469 Rebuild Kit

The ASCO 323-469 Rebuild Kit is a critical maintenance solution designed for the ASCO 8262 series and 8263 series 2-way solenoid valves. Engineered for normally closed operation, this kit allows technicians to restore factory-standard performance and seal integrity without replacing the entire valve body. It features a high-grade Buna-N (NBR) diaphragm and seals, ensuring chemical compatibility with air, water, and light oil applications. The kit includes the core assembly, springs, and O-rings necessary for a complete overhaul. Utilizing this ASCO valve repair kit prevents internal leakage and ensures precise solenoid seat seating, minimizing downtime in high-cycle industrial environments. Given the tight tolerances of direct-acting solenoid valves, using OEM components is essential for maintaining the designated MOPD (Maximum Operating Pressure Differential) and preventing premature coil burnout due to mechanical resistance.

Key Benefits

• Includes OEM-spec internal components for precise fitment in 8262 and 8263 series valves.
• High-durability Buna-N seals provide reliable performance in standard temperature and pressure ranges.
• Reduces operational overhead by enabling field-service repairs rather than full valve replacement.
• Ensures consistent flow coefficients (Cv) and rapid response times in automated systems.

Common Questions

What is included in the ASCO 323-469 repair kit?
This kit typically contains the solenoid core, disc-holder assembly, core spring, and all necessary NBR O-rings and gaskets for a total internal rebuild.

Can this kit be used for high-temperature steam applications?
No, the Buna-N elastomer is rated for standard air, water, and oil. For high-temperature or corrosive media, verify compatibility with EPDM or Viton alternatives.

How do I identify if my valve requires the 323-469 kit?
Verify the rebuild kit number on the original valve nameplate; this kit specifically services many 1/8 inch and 1/4 inch ASCO RedHat 2-way NC models.
