GC Valves S211GF02N5FG9 Valve

The GC Valves S211GF02N5FG9 is a high-performance, 2-way normally closed solenoid valve engineered for reliable fluid control in commercial and industrial HVACR systems. This unit features a robust brass body with a 1-inch NPT connection and a full 1-inch orifice, ensuring optimal flow characteristics for water, air, and light oil applications. Operating on a 120Vac power supply, the valve utilizes a Class F coil rated for high-temperature environments, providing consistent actuation under heavy duty cycles. The Nitrile (Buna-N) seal material offers excellent chemical resistance and leak-proof performance within standard temperature ranges. This model serves as the direct technical successor to the legacy S211AF02N5FG9, maintaining the same form factor while integrating improved internal components for enhanced field reliability. When installing, ensure the pressure differential meets the minimum operational requirements to guarantee full diaphragm lift and seating.

Technical Specifications & Benefits

• Drop-in Replacement: Seamlessly replaces the discontinued S211AF02N5FG9 without necessitating piping modifications.
• High Flow Capacity: Large 1" orifice supports high Cv flow coefficients for demanding installations.
• Industrial Grade Insulation: Class F coil rating ensures thermal stability during continuous energization.
• Media Compatibility: Nitrile seals provide a versatile solution for neutral fluids and pneumatic systems.
• Reliable Actuation: Designed for standard 120V 60Hz electrical circuits typical in North American HVACR control panels.

Common Installation Questions

What is the difference between the S211GF02N5FG9 and the older S211AF02N5FG9?
The GF-series is the current production standard featuring upgraded coil housing and internal geometry for better longevity, while maintaining full dimensional compatibility with the AF-series hardware.

Does this valve require a minimum pressure differential to operate?
Yes, as a pilot-operated diaphragm solenoid valve, it requires a minimum pressure drop (typically 5-10 PSI) across the inlet and outlet to ensure the valve opens and closes reliably.

Can this GC Valve be mounted in any orientation?
For maximum service life and to prevent debris accumulation in the plunger tube, it is recommended to install the valve with the solenoid coil in the upright vertical position.
