GC Valves KS201AF02C5CG4 Repair Kit

The GC Valves KS201AF02C5CG4 Repair Kit is a professional-grade solution for restoring the performance of S201 series solenoid valves. Designed for 2nd generation S201 normally closed, piloted valves, this kit addresses common failure points such as internal leakage and sluggish cycling. As a solenoid valve rebuild kit, it provides the critical internal components necessary to return your hardware to its original operating specifications without requiring a full valve body replacement. Each kit includes a primary diaphragm assembly, a precision-engineered plunger assembly, a plunger tube, and the essential O-rings for a gas-tight seal. By replacing these wear-prone internal parts, technicians can ensure a positive shutoff and reliable flow control in high-demand environments like car washes, water treatment plants, and HVACR systems. This universal repair kit is compatible with S201GF series valves utilizing C5CG4 or C5DG4 coil configurations, featuring Buna-N (NBR) elastomeric seals for standard fluid and gas applications. Utilizing OEM GC Valves parts ensures component geometry aligns perfectly with existing 3/8-inch brass valve bodies, maintaining system integrity under continuous duty cycles.

Key Benefits:

• Full Internal Restoration: Contains plunger assembly, diaphragm, and body O-rings to resolve sluggish operations and internal bypass.
• Optimized Compatibility: Specifically engineered for GC Valves S201 series, ensuring the spring rates and plunger lift heights match factory specs.
• Reduced Downtime: Modular components allow for rapid field service of normally closed solenoid valves without removing the valve body from the piping.
• Durable Sealing: High-grade Buna elastomeric components provide excellent resistance to standard liquids, oils, and gases.
• Cost-Effective Maintenance: Avoid the expense of total valve replacement by targeting the solenoid rebuild at the component level.

Common Questions:

What valves are compatible with the KS201AF02C5CG4 kit?
This kit is designed for the GC Valves S201 series solenoid valves, particularly those with C5CG4 or C5DG4 catalog suffixes. It is primarily used for AC-powered, piloted piston-operated valves.

Should I choose a repair kit or a full rebuild kit?
A repair kit typically contains the seat disc, diaphragm, and O-rings, whereas a rebuild kit includes the plunger, spring, and plunger tube. This KS201AF02C5CG4 is a comprehensive 2nd generation kit that covers most internal moving parts for a thorough overhaul.

Does the kit include the solenoid coil?
No, this is an internal valve repair kit. If you are experiencing electrical failure or a burnt-out coil, you must purchase the appropriate S4 solenoid coil separately.
