GC Valves KS211AF02L7GJ2 Repair Kit

The GC Valves KS211AF02L7GJ2 Repair Kit is a critical maintenance solution for high-performance S211 Series 2-way normally closed solenoid valves. Designed for industrial fluid control, this kit features Viton (FKM) seals, providing superior chemical resistance and thermal stability for media temperatures ranging from 32°F to 230°F. As a veteran-grade solenoid valve repair kit, it includes the essential components to resolve internal leakage and restore positive shutoff, specifically a high-grade diaphragm assembly, seat disc, and required O-rings. Professionals typically employ this kit for S211GF and S211AF valve bodies with 1-1/4 inch NPT connections to ensure zero-leakage performance without replacing the entire valve body. Integrating these OEM GC Valves parts maintains the original Cv flow coefficient and operational differential pressures across air, gas, and liquid applications. Precise installation of the Viton diaphragm ensures long-term reliability in aggressive media environments where standard Nitrile or EPR elastomers might fail prematurely under high-cycling demands.

Key Benefits

• Chemical Resistance: Equipped with Viton (FKM) seals for compatibility with oils, chemicals, and high-temperature fluids.
• Full Restoration: Includes the diaphragm assembly and seat disc to eliminate internal bypass and sluggish operation.
• In-Line Maintenance: Engineered for rapid replacement while the valve body remains in the piping system, reducing downtime.
• OEM Compatibility: Specifically calibrated for GC Valves S211 Series piloted diaphragm valves to match original factory specifications.

Common Questions

What is included in the KS211AF02L7GJ2 kit versus a full rebuild kit?
This repair kit focuses on primary wear components: the seat disc, O-rings, and diaphragm assembly. It is designed to address elastomer wear. If the plunger tube or spring is damaged, a full rebuild kit would be required instead.

How do I ensure the Viton seal is the right choice for my application?
Viton (FKM) is the industry standard for applications involving oils, fuels, and temperatures up to 230°F. If you are handling steam or high concentrations of ketones, you should verify if EPR or PTFE alternatives are more suited for your specific media.

Can this kit be used on both AC and DC solenoid valves?
Yes, because the internal elastomer components and diaphragm structures are identical between AC and DC models of the same series, this repair kit is cross-compatible regardless of the coil voltage.
