ASCO 314-479 Rebuild Kit

The ASCO 314-479 Rebuild Kit is a comprehensive field-service solution specifically engineered for the maintenance and restoration of ASCO Series 314 direct-acting solenoid valves. As a veteran-grade solenoid valve repair kit, it provides the essential internal components required to address common failure points such as internal leakage or sluggish actuation in 3-way piloting applications. This kit is designed for high-cycle environments where maintaining the integrity of the NBR seals and FPM discs is critical for hydraulic and pneumatic system reliability.

By replacing the core assembly, springs, and elastomer seals using this ASCO valve maintenance kit, technicians can restore original factory specifications without the need for full valve replacement. The components are optimized for general service media, including air, inert gas, water, and light oil, supporting a wide range of industrial and HVACR fluid control configurations. This kit ensures your 3-way universal solenoid continues to operate with no minimum pressure requirement, maintaining the high-speed response times necessary for precision actuator control.

• Complete internal parts replacement including diaphragms, springs, and O-rings for total valve overhaul.
• Restores leak-tight shutoff and optimal flow coefficients (Cv) in 3/2 normally closed or universal configurations.
• Compatible with ASCO 8314 series valves utilizing AC-rated solenoid coils.
• Engineered for high-viscosity resistance up to 65 cSt, ensuring performance across diverse fluid types.
• Reduces system downtime by allowing for fast, onsite pneumatic valve rebuilds.

• How do I know if the ASCO 314-479 is compatible with my specific valve body? Compatibility depends on the catalog prefix and size. This kit is typically used for 1/8" to 1/4" NPT Series 314 valves; always verify the voltage and construction code on your valve nameplate.
• Does this kit include a replacement solenoid coil? No, this kit focuses on the mechanical internal components and seals. If the coil is burnt or shorted, it must be sourced separately based on your specific voltage requirements.
• Can this kit be used for oxygen-clean service applications? While some 314 series valves are rated for oxygen service, standard NBR/FPM kits may not meet specific degreasing requirements. Consult the manufacturer if your system requires dedicated oxygen-compatible seals.
