ASCO 302-280 Rebuild Kit

The ASCO 302-280 Rebuild Kit is a critical maintenance solution designed for the ASCO 8302 series 2-way hung diaphragm solenoid valves. This comprehensive kit includes a high-grade NBR (Buna-N) diaphragm, stainless steel core springs, and necessary seals to restore factory-spec pressure containment and flow control. Engineered for compatibility with 1/2" NPT valve bodies, the components handle differential pressure ranges typical in water, light oil, and air applications. Replacing the internal elastomers and mechanical wear points ensures the solenoid seat maintains an airtight seal, preventing internal leakage and extending the service life of the valve body. For contractors servicing normally closed configurations, this kit provides the precise tolerances required to prevent chatter and ensure reliable cycling under varying thermal loads. Regular installation of the 302-280 kit prevents catastrophic failure in automated fluid control systems by addressing diaphragm fatigue and spring tension loss.

Key Benefits

• Optimized Sealing: High-performance NBR diaphragm ensures broad chemical compatibility with non-corrosive fluids.
• Precision Fit: Specifically machined components for ASCO 8302 series to eliminate bypass leakage.
• Extended Service Life: Industrial-grade springs and solenoid rebuild components resist mechanical fatigue.
• Simplified Maintenance: Includes all internal wear parts required for a complete top-end overhaul.

Common Questions

How do I know if my 8302 series valve requires a rebuild?
Common indicators include audible internal leaking, failure of the valve to fully close against rated pressure, or sluggish response times during coil energization.

Is the 302-280 kit compatible with high-temperature steam?
No, this kit utilizes Buna-N elastomers. For high-temperature or steam applications, an EPDM or Viton-based kit may be required depending on the specific valve body rating.

Does this kit include the solenoid coil?
The 302-280 is a mechanical rebuild kit focusing on the diaphragm and internal seals; the electrical solenoid coil is sold separately if replacement is needed due to burnout.
