GC Valves KS211AF02N5EG5 Repair Kit

The GC Valves KS211AF02N5EG5 Repair Kit is a professional-grade maintenance solution engineered specifically for 3/4 inch S211 series solenoid valves. Designed for high-cycle industrial environments, this kit allows technicians to perform a full diaphragm replacement without removing the valve body from the line, minimizing system downtime. The S211 series operates as a 2-way normally closed piloted diaphragm valve, and this kit includes a high-performance diaphragm assembly and the essential O-rings required to restore a bubble-tight seal. Utilizing GC Valves replacement parts ensures consistent flow control and maintains the original Cv rating of 6.1 across various media, including air, inert gas, and water. For HVACR professionals managing process cooling or water treatment systems, this solenoid valve rebuild kit is the standard for correcting internal leaks or sluggish actuation. By installing these factory-spec components, you ensure the plunger and diaphragm respond accurately to the 10-watt S4 coil's electromagnetic field, preventing premature coil burnout caused by mechanical resistance.

• Direct Compatibility: Formulated specifically for 3/4 S211 solenoid valves, ensuring a precision fit for the valve bonnet and internal seating surfaces.
• Technical Restoration: Includes a high-durability diaphragm and resilient O-rings to handle operating pressures up to 150 PSI for water and 250 PSI for air.
• Efficient Servicing: Simplifies the solenoid maintenance process with drop-in components, reducing the labor required for field repairs.
• Chemical Resistance: Materials are selected for compatibility with a variety of neutral gases and liquids within an ambient temperature range of 32°F to 125°F.

What is the difference between a rebuild kit and this repair kit for the S211?
While a rebuild kit typically includes the plunger and tube assembly, this KS211AF02N5EG5 repair kit focuses on the primary wearing components: the diaphragm assembly and the O-ring seals. It is the preferred choice for resolving external housing leaks or failure to close tightly.

Does this kit work for all 3/4 inch GC Valves?
No, this kit is specifically designed for the S211 series. Always verify the catalog number on the valve nameplate. For S201 or other high-pressure series, a different kit configuration is required to match the orifice size and stroke length.

When should I replace the diaphragm in my S211 valve?
Technicians should inspect the diaphragm during routine maintenance or if the valve exhibits "hunting" or delayed shut-off. Hardened or torn diaphragms are common in systems with high sediment or extreme temperature cycling.
