GC Valves KS211AF02N5FG9 Repair Kit

The GC Valves KS211AF02N5FG9 Repair Kit is a comprehensive maintenance solution engineered for high-performance S211 series solenoid valves. Specifically designed for 1-inch NPT brass valve bodies, this kit provides technician-grade components to restore factory-spec pressure regulation and flow control. The assembly features a high-density Buna-N diaphragm (Nitrile), providing superior elastomeric resilience and sealing performance for air, water, and non-corrosive fluid applications. This OEM solenoid valve rebuild kit is critical for resolving common maintenance issues such as internal leakage, sluggish actuation, or "humming" caused by debris accumulation or mechanical fatigue in the plunger seat. By replacing the internal plunger assembly and diaphragm assembly, contractors can ensure precise piloting and shut-off integrity in demanding industrial and HVACR environments without the cost profile of a full valve body replacement. Each component is manufactured to strict tolerances to maintain the normally closed (N.C.) operational logic of the S21 series.

• Precision Compatibility: Specifically sized for 1-inch GC Valves S211 series AC valves ending in N5FG9.
• Elastomeric Durability: Includes a premium Buna-N diaphragm for reliable performance across standard temperature ranges.
• Complete Maintenance Set: Contains the diaphragm assembly, plunger spring, plunger tube, and all necessary body O-rings for a leak-proof seal.
• Optimized Flow Control: Restores original Cv factors and prevents pressure drop issues caused by worn internal seating surfaces.

Does this kit include the plunger tube and spring?
Yes, as a full rebuild-style kit, it includes the plunger tube, plunger assembly, and the return spring to ensure the valve returns to its normally closed position effectively.

Will this work with Viton or EPR specific valves?
This specific kit (N5 suffix) utilizes Nitrile (Buna-N) seals. If your application involves high-temp steam or aggressive chemicals requiring Viton seals, you should verify the compatibility of the elastomer with your specific media before installation.

Can I install this without removing the valve body from the pipeline?
Yes, these GC Valves are designed for top-entry maintenance. Simply de-energize the coil and remove the bonnet bolts to access the internal components for a rapid field repair.
