GC Valve S211GF02N5JJ2 Solenoid Valve

The GC Valve S211GF02N5JJ2 Solenoid Valve is a heavy-duty, 2-way piloted diaphragm valve engineered for high-capacity fluid control in demanding industrial and HVACR environments. Built with a rugged brass body and a 2-inch NPT connection, this normally closed solenoid valve is designed to handle air, inert gases, water, and light oils with a substantial 1 1/4-inch orifice providing a high flow coefficient (Cv) of 28. The 120Vac coil features Class F insulation, ensuring reliable operation in ambient temperatures up to 125°F and media temperatures reaching 180°F. The Nitrile (Buna-N) seal material offers superior resistance to hydrocarbons, making it a preferred choice for fuel oil and pneumatic applications. This unit requires a minimum 5 psi pressure differential to actuate and supports maximum operating pressures up to 200 psi for air and 150 psi for water, delivering precise, bubble-tight shutoff for critical process control systems.

• Durable Brass Construction: High-strength brass body solenoid valve provides excellent corrosion resistance and longevity in hydronic and commercial plumbing systems.
• High-Flow Design: Large 1 1/4-inch orifice allows for significant flow rates, minimizing pressure drop across the 2" NPT line.
• Standard Electrical Compatibility: Equipped with a 120V solenoid coil and NEMA 4X conduit housing for easy integration into existing control circuits.
• Resilient Media Handling: Nitrile seals ensure compatibility with a wide range of neutral fluids and light oils, preventing premature seal degradation.

• What is the minimum pressure required for this valve to open? As a piloted diaphragm valve, the S211GF02N5JJ2 requires a minimum differential pressure of 5 psi to lift the diaphragm and allow flow.
• Can this valve be mounted in any orientation? For optimal performance and to prevent sediment build-up in the pilot orifice, it is highly recommended to mount the valve with the solenoid coil in a vertical and upright position.
• Is this valve suitable for steam applications? No, the Nitrile seal material and Class F coil are rated for a maximum fluid temperature of 180°F. For steam service, a valve with EPDM or PTFE seals and a Class H coil is required.
