GC Valves KS301AF02N2AC3 Repair Kit

The GC Valves KS301AF02N2AC3 Repair Kit is a professional-grade rebuild solution engineered specifically for S301 series solenoid valves. This direct-acting valve rebuild kit is designed for high-cycle industrial applications where maintaining positive shutoff and pressure integrity is critical. This comprehensive kit features Buna-N (NBR) elastomeric components, providing excellent resistance to oil, water, and various gases within standard temperature ranges. The assembly includes a precision-machined plunger, a spring and seat disc assembly, and a matched plunger tube to ensure exact stroke alignment. By replacing core internal components, technicians can restore bubble-tight sealing performance and prevent common issues like sluggish operation or internal leakage caused by particulate debris or mechanical wear. Tailored for 1/8" stainless steel or brass body configurations, this kit ensures full electrical and mechanical compatibility with 120V/60Hz AC solenoid operators, eliminating the risk of coil burnout associated with mismatched internal tolerances and spring rates.

• Full System Restoration: Includes the plunger assembly, operator O-rings, and plunger tube to solve seating issues at the source.
• Material Compatibility: High-performance Buna-N elastomers ensure chemical resistance for general-purpose fluid and air control.
• Optimized Coil Performance: Correct spring tension and plunger mass prevent overheating and solenoid coil failure.
• Direct Fit: Specifically calibrated for GC Valves S301 2-way normally closed valve bodies for seamless field installation.

Does this kit work for DC voltage versions of the S301 valve?
No, this specific rebuild kit is configured with AC-rated internal components. While the elastomers may be similar, the plunger and spring assembly are tuned for 120VAC operations to prevent hum and maintain proper magnetic flux. Verify your coil's voltage before installation.

When should I use a rebuild kit instead of just a repair kit?
A solenoid valve rebuild is recommended when you observe physical wear on the plunger tube or if the valve remains stuck partially open. While a standard repair kit covers only seals, this rebuild kit replaces the plunger and tube, which are critical for smooth mechanical travel in high-pressure systems.

Is a special tool required for installation?
To avoid damaging the valve body, we recommend using a GC Valves spanner nut or a similar specialized wrench to remove the solenoid base nut and plunger tube without distorting the stainless steel housing.
