ASCO 302-307 Rebuild Kit

The ASCO 302-307 Rebuild Kit is a comprehensive maintenance solution designed for the 8302 and 8307 series 3-way solenoid valves. This factory-authorized kit ensures critical seal integrity and consistent actuation in high-cycle pneumatic control and process automation applications. Technical components typically include a precision-machined core assembly, high-grade NBR or Viton diaphragms, and stainless steel return springs to restore original manufacturer specifications. By replacing worn internal components, technicians can eliminate internal leakage and prevent pressure drop across the valve body. This kit is essential for maintaining system reliability in harsh industrial environments where downtime is not an option. Proper installation of the disc-holder and O-rings restores the valve's operating pressure differential and flow capacity (Cv), extending the service life of the existing valve body without the need for full pipework disassembly.

• Restores sealing integrity to prevent cross-port leakage in 3-way configurations.
• Includes OEM-grade elastomers for chemical compatibility and temperature resistance.
• Optimizes valve response time by replacing fatigued springs and worn core tubes.
• Reduces operational downtime by facilitating rapid on-site maintenance.
• Ensures compliance with ASCO flow ratings and pressure specifications.

Is this kit compatible with high-temperature steam applications?
Compatibility depends on the elastomer material included; standard NBR kits are rated for air and water, while FKM/Viton versions are required for higher temperature chemical or steam media.

Does this kit include the solenoid coil?
No, this is a mechanical rebuild kit containing internal wear parts like diaphragms and springs; coils must be sourced separately based on voltage requirements.

Can I use this for both AC and DC valve versions?
While many mechanical parts are interchangeable, always verify the valve prefix and serial number as some spring tensions differ between AC and DC solenoid operators.
