GC Valves S211GF02K4CG1 Valve

The GC Valves S211GF02K4CG1 is a high-performance, 2-way normally closed solenoid valve specifically engineered for demanding HVACR and industrial fluid control applications. Built with a rugged forged brass body and a 10-watt Class F encapsulated coil, this pilot-operated diaphragm valve ensures reliable cycling even in high-duty environments. The 3/8" NPT connection and 1/2" orifice provide a generous 4.3 Cv flow coefficient, making it an ideal choice for managing large volumes of air, inert gas, water, and light oils. Integrated FKM (Viton) seals allow for a maximum media temperature of 230°F, offering superior chemical resistance compared to standard nitrile components. Designed for versatility, this S21 series unit supports an operating pressure differential of up to 250 PSI for air/gas and 150 PSI for liquids. Contractors value the 1/2" conduit electrical connection for secure NEMA 4X installations, ensuring the 120V/60Hz magnetic actuator remains protected against environmental contaminants on the job site.

Key Benefits

• Optimized Flow Dynamics: Features a high 4.3 Cv rating and a 1/2" orifice to minimize pressure drop across the 3/8" NPT ports.
• Extreme Temperature Rating: Equipped with FKM seals to handle aggressive media and temperatures reaching 230°F.
• Industrial-Grade Casting: The heavy-duty brass construction provides the durability required for commercial steam and water systems.
• Advanced Coil Protection: The Class F coil is housed in a 1/2" conduit NEMA 4X enclosure for maximum moisture and dust resistance.
• Anti-Water Hammer Design: Engineered to provide smooth closing or opening transitions, reducing mechanical stress on downstream piping.

Common Questions What is the minimum pressure required for operation? As a pilot-operated diaphragm valve, the S211GF02K4CG1 typically requires a minimum pressure differential of 4 to 5 PSI to successfully lift the diaphragm and maintain a fully open state. Can this valve be mounted in any orientation? While these solenoid valves are multi-poised, it is best practice for technicians to mount the unit with the solenoid in a vertical, upright position to prevent sediment buildup in the plunger tube. Is this solenoid compatible with aggressive media? Yes, the combination of a brass body and FKM (Viton) sealing makes this model highly effective for "slightly aggressive" media, including hot water, steam, and certain light oils that would degrade standard elastomers.
