GC Valves KS201AF02C5EG5 Repair Kit

The GC Valves KS201AF02C5EG5 Repair Kit is a comprehensive rebuild solution for the S201 series solenoid valves, specifically engineered for 2-way normally closed operations. This kit addresses common failure points in solenoid valve maintenance, including worn diaphragms and sluggish plunger response. Featuring a high-grade EPDM diaphragm, this rebuild kit is optimized for water, air, and low-pressure steam applications where chemical compatibility and thermal stability are critical. The stainless steel plunger and precision-wound spring ensure consistent seating force, preventing internal leakage and maintaining original flow coefficient (Cv) ratings. Professional contractors rely on this kit for HVAC valve repair and fluid control systems to restore factory-spec pressure ratings and response times without the logistical cost of a full valve body replacement. Each component is manufactured to strict tolerances to ensure a perfect fit with the S201 valve's internal geometry and 1/2-inch or 3/4-inch port configurations.

• Optimized Sealing: High-resiliency EPDM elastomer provides superior resistance to heat and aging compared to standard nitrile components.
• Direct OEM Fitment: Engineered specifically for the S201AF02 series, eliminating the risk of bypass or improper seating associated with generic kits.
• System Reliability: Restores solenoid coil efficiency by ensuring the plunger stroke is unobstructed and the return spring tension meets factory benchmarks.
• Installation Efficiency: Contains all necessary internal wear parts to complete a solenoid rebuild in the field, minimizing system downtime.

What media is this repair kit compatible with?
The EPDM components are designed for water, air, and specific chemical applications. Verify that your media is compatible with EPDM to prevent premature seal swelling or degradation.

Does this kit include the replacement coil?
No, this is a mechanical rebuild kit containing the diaphragm, plunger, springs, and O-rings. If you are experiencing electrical failure, the coil must be tested and purchased separately.

Can this be used for normally open valve configurations?
This specific kit is calibrated for normally closed S201 series valves. Using these internals in a normally open body will result in incorrect valve operation and potential safety risks.
