ASCO 310-635 Rebuild Kit

The ASCO 310-635 Rebuild Kit is a comprehensive maintenance solution designed for series 8210 and 8211 2-way solenoid valves. Engineered for normally closed (NC) operation, this kit allows technicians to perform a full internal component replacement, ensuring the valve maintains its zero differential pressure rating. The kit includes a high-performance NBR (Buna-N) diaphragm and seal assembly, specifically selected for its resilience in standard air, water, and light oil applications. By replacing the solenoid core, spring, and elastomers, you restore the original sealing integrity and response time of the pilot-operated valve. This field-serviceable kit is critical for preventing leak-through and ensuring reliable seat closure during high-cycle demands in HVACR systems. Utilizing genuine ASCO spare parts ensures exact tolerances are met, maintaining the valve's CV flow coefficient and operational specifications without requiring full body replacement.

• Direct OEM Compatibility: Specifically calibrated for ASCO 8210 series 1/2" to 3/4" pipe sizes.
• High-Grade Elastomers: Features NBR seals for excellent chemical resistance in neutral fluid applications.
• Operational Efficiency: Restores performance for internal pilot-operated configurations requiring minimal pressure lift.
• Reduced Downtime: Includes all necessary internal valve components for a rapid field rebuild.

• Does this kit work with high-temperature steam applications? No, the ASCO 310-635 utilizes NBR seals; for high-temp or steam, an EPDM or Viton kit tailored for the specific valve prefix is required.
• Can I use this rebuild kit on a normally open (NO) valve? No, this kit is specifically designed for the normally closed internal geometry of the 8210 and 8211 series.
• Are the solenoid coils included in the 310-635 kit? This is a mechanical rebuild kit for the valve internals; electrical coils must be sourced separately based on voltage requirements.
