GC Valves S211AF16N5GJ2 Solenoid Valve

When you're dealing with high-capacity fluid or gas control, the GC Valves S211AF16N5GJ2 Solenoid Valve is a reliable, industrial-grade workhorse designed for the heavy-duty demands of HVACR and process systems. This 2-way piloted diaphragm solenoid valve features a robust brass body and a full 1 1/4" orifice, providing the high flow rates (Cv) necessary for large-scale applications. With its normally closed configuration, it ensures a positive shut-off via a spring-loaded plunger, making it ideal for safety-critical installations where flow must stop upon power loss.

The valve is equipped with a 24Vdc coil (Class F insulation), providing stable actuation in DC control circuits. Its Nitrile seal material (Buna-N) offers excellent compatibility with air, water, and light oils at pressures up to 150 PSI. For the veteran contractor, the 1 1/4" NPT ports and multi-poise mounting capabilities mean straightforward integration into existing manifolds or piping runs. Whether you’re managing water treatment systems or industrial cooling loops, this GC Valves S211 series component is engineered for field durability and ease of maintenance.

• High-Flow Efficiency: The 1 1/4" orifice and piloted diaphragm design minimize pressure drop in high-volume systems.
• Durable Construction: Heavy-duty brass body and Nitrile seals provide long-term reliability in standard media applications.
• Standardized Power: The 24Vdc solenoid integrates seamlessly with modern industrial PLC and DC control logic.
• Serviceable Design: Features a replaceable Class F coil and accessible internal components for routine field cleaning.

• What is the maximum operating pressure differential (MOPD)? This model is typically rated for up to 150 PSI, making it suitable for most pressurized liquid and gas lines.
• Can this valve be mounted in any orientation? Yes, the S211 series is multi-poise, though mounting with the solenoid vertical and upright is the preferred industry practice.
• Why is the valve chattering or buzzing? This is usually caused by low voltage to the 24Vdc coil or debris trapped between the plunger and the tube head; clear the lines of foreign matter before installation.
