GC Valves S272AF02N5FG9 Valve

The GC Valves S272AF02N5FG9 is a high-performance, 2-way normally open solenoid valve designed for rugged HVACR and industrial fluid control. Featuring a 1-inch NPT connection and a 1-inch orifice, this brass body solenoid valve is engineered for high-flow applications involving air, water, and light oils. The pilot-operated diaphragm design ensures reliable operation with a zero differential capability, meaning it functions effectively even at low pressures. Built with a Class F coil rated for 120Vac, this unit is optimized for continuous duty in demanding environments. The Nitrile (Buna-N) seal material provides excellent chemical resistance and a tight shut-off, making it a go-to choice for contractors maintaining water treatment systems, cooling loops, or pneumatic lines. Its robust construction supports a maximum operating pressure of 125 PSI for air and water, ensuring this normally open valve stays open until energized, providing a critical fail-safe position for specific system architectures.

• High-Flow Capacity: The 1-inch orifice and NPT porting provide a high Cv rating for efficient media transfer with minimal pressure drop.
• Zero Pressure Differential: Designed to operate reliably from 0 PSI up to the maximum rated pressure, ideal for gravity-fed or low-pressure systems.
• Durable Brass Construction: The heavy-duty brass body and stainless steel pilot orifice offer superior corrosion resistance and longevity in the field.
• NEMA 1 Conduit Housing: Standard 18-inch leads and a conduit-ready electrical enclosure simplify integration into existing control circuits.
• Thermal Management: The Class F coil is rated for higher ambient temperatures, preventing premature coil burnout during extended run cycles.

What is the fail-safe position of this valve?
This is a normally open (N/O) valve, meaning flow is permitted when the coil is de-energized. It requires a constant 120V signal to close the valve and stop the flow.

Can this valve be used for steam applications?
While the brass body is robust, the Nitrile seals in the S272AF02N5FG9 are rated for air, water, and light oil. For high-temperature steam applications, a Viton or EPR seal variant is typically required.

What is the proper mounting orientation?
For optimal performance and to prevent sediment buildup in the pilot orifice, the valve should be mounted in a vertical and upright position with the solenoid housing on top.
