GC Valve S211GF16N5JJ2 Valve

The GC Valve S211GF16N5JJ2 is a high-performance, 2-way piloted diaphragm solenoid valve engineered for heavy-duty industrial and HVACR fluid control. Featuring a 2" NPT connection and a 1-1/4" orifice, this normally closed solenoid valve provides exceptional flow capacity with a 28 Cv flow coefficient. Constructed with a rugged brass body and high-grade nitrile seal material (Buna-N), it is purpose-built to handle air, inert gas, water, and light oil. The 24Vdc coil is rated for Class F insulation, supporting a maximum fluid temperature of 180°F. Designed for reliability in pressurized systems, this pilot operated valve requires a minimum pressure differential of 5 psi to function effectively, reaching a maximum operating pressure differential of 150 psi for water and air. Whether utilized in commercial irrigation, large-scale plumbing, or industrial process cooling, the S211 series delivers precise regulation and positive shutoff for veteran contractors demanding consistent field performance.

• Optimized Flow Dynamics: The 1-1/4" orifice and piloted diaphragm design provide a high flow-to-size ratio, minimizing pressure drop across the line.
• Industrial-Grade Durability: The heavy-duty brass construction resists corrosion in neutral media environments, ensuring longevity in demanding service conditions.
• Versatile Media Handling: Compatible with a wide range of fluids, including light oils and treated water, making it a versatile component for diverse mechanical systems.
• Reliable Electrical Performance: The Class F encapsulated conduit coil is built to withstand higher thermal loads in continuous-duty applications.

What is the minimum pressure required for this valve to open?
As a pilot operated solenoid valve, the S211GF16N5JJ2 requires a minimum pressure differential of 5 psi to lift the diaphragm and allow flow. It will not function in gravity-fed or zero-pressure systems.

Can this valve be mounted in any orientation?
While the S211 series is multi-poise and can be mounted in various positions, it is best practice for technicians to install the valve with the solenoid operator in a vertical and upright position to prevent sediment accumulation in the core tube.

Is the nitrile seal compatible with high-temperature steam?
No, the nitrile (Buna-N) seals in this model are rated for a maximum fluid temperature of 180°F. For steam or aggressive chemical applications, a valve with Viton or PTFE seals would be required to prevent premature seal failure.
