ASCO 302-183 Rebuild Kit

The ASCO 302-183 Rebuild Kit is a comprehensive diagnostic and repair solution designed for the 8320 series 3-way solenoid valves. As a veteran-grade service kit, it provides the essential internal components required to restore factory-spec pressure ratings and bubble-tight shutoff in high-cycle HVACR and industrial pneumatic applications. This kit is specifically engineered for AC-powered solenoid valves and includes a precision-machined core assembly, high-fatigue core spring, and a complete set of NBR (Buna-N) gaskets and seals to eliminate internal bypass and external leakage.

When performing field maintenance on the ASCO 8320 AC Series, replacing the entire internal stack rather than individual O-rings ensures long-term reliability and reduces the risk of solenoid hum or sticking. This genuine ASCO spare parts kit is compatible with valves utilizing a screw-type manual operator (MO/MS suffix) or standard general-purpose enclosures. By utilizing this solenoid valve repair kit, contractors can extend the service life of existing brass or stainless steel valve bodies without the labor-intensive process of re-piping the entire assembly. Always verify the rebuild kit number on the valve nameplate before installation to ensure exact fitment for proper valve reassembly.

Key Benefits:

• Includes mandatory core spring and core assembly to prevent valve failure under high-pressure differentials.
• Maintains official ASCO solenoid valve performance standards for 3-way flow control.
• Comprehensive seal package with Buna-N elastomers for superior compatibility with air, water, and light oils.
• Optimized for 8320 series AC-coil configurations to ensure low-noise operation and rapid response times.
• Reduces downtime by providing all critical solenoid maintenance parts in a single SKU.

Common Questions:

How do I know if this kit is compatible with my specific 8320 valve?
Always cross-reference the rebuild kit number stamped on your valve’s nameplate. If the nameplate is unreadable, check for the "8320" series designation and verify if your unit uses an AC coil, as DC versions often require different internal spring tensioning.

Does this kit include a replacement solenoid coil?
No, this is a mechanical rebuild kit. It contains the internal moving parts (core, springs) and stationary seals. If your valve is failing to energize due to an electrical fault, a separate ASCO replacement coil may be necessary.

Can I use this kit for valves handling steam or high-temperature fluids?
The ASCO 302-183 utilizes standard NBR seals. For high-temperature or steam service, you must verify that your fluid temperature does not exceed the elastomer's rating; typically, EPDM or Viton (FKM) kits are required for those specific media.
