ASCO 302-336 Rebuild Kit

The ASCO 302-336 Rebuild Kit is a comprehensive maintenance solution designed for the 8210 Series 2-way solenoid valves. Engineering specifically for 3/4-inch and 1-inch NPT valve bodies, this ASCO valve repair kit includes the essential internal components needed to restore factory-spec sealing and cycle reliability. The kit features a high-grade Buna-N (NBR) diaphragm, which provides excellent resilience in standard water, air, and light oil applications. As a genuine ASCO replacement part, it ensures proper fitment of the core assembly, springs, and gaskets, eliminating the pressure drop and internal leakage issues common in aged pilot-operated valves. This rebuild kit allows technicians to perform a full internal overhaul without removing the valve body from the piping, reducing downtime on HVACR systems and industrial fluid control lines. Using the ASCO 302-336 ensures your 8210G002 or 8210G094 units maintain optimal flow dynamics and bubble-tight shutoff performance in demanding environments.

Key Benefits for Contractors

• OEM Compatibility: Precision-engineered for ASCO 8210 series rebuild projects, ensuring no mismatch in spring tension or diaphragm seat.
• Enhanced Sealing: The NBR diaphragm assembly provides superior resistance to typical non-corrosive fluid media.
• Installation Efficiency: Contains all necessary solenoid valve internal parts to complete a rebuild in a single service call.
• Operational Reliability: Restores the pilot-operated mechanism to prevent sticking and intermittent coil failure.

Common Questions & Troubleshooting

Does this kit work for high-temperature steam applications?
No, the 302-336 utilizes Buna-N elastomers. For high-temp steam, you must specify an ASCO kit with EPDM or Viton components compatible with the specific 8210 variant.

What causes a valve to fail to open after installing a rebuild kit?
Commonly, this is due to debris in the pilot orifice or improper seating of the core spring. Ensure the valve body is flushed and the ASCO rebuild kit components are oriented exactly per the technical schematic.

How do I identify if my 8210 valve requires the 302-336 kit?
Verify the rebuild kit number on the valve nameplate. This kit is specifically sized for the 3/4" and 1" NPT pilot-operated 8210 series valves with standard elastomers.
