GC Valves S271AF02C5JJ2 Valve

The GC Valves S271AF02C5JJ2 is a heavy-duty, 2-way normally closed solenoid valve engineered for precision fluid control in demanding industrial and HVACR environments. Featuring a rugged 2-inch NPT brass body and a substantial 1-1/4 inch orifice, this valve is optimized for high-flow applications involving hot water and steam. The EPR (Ethylene Propylene Rubber) seal material provides excellent chemical resistance and thermal stability for media temperatures up to 295°F, making it a reliable choice for boiler feed lines and heat exchange systems. Driven by a 120Vac Coil Class F, the unit is built to withstand continuous duty cycles in high-ambient conditions. As a zero-differential piloted diaphragm valve, it ensures consistent operation even in low-pressure systems. For contractors managing large-scale hydronic or steam-process installations, the S27 series delivers the industrial-grade performance required to maintain system integrity and prevent costly downtime.

• High-Flow Capacity: The 1-1/4" orifice and 2" NPT ports support significant gallon-per-minute (GPM) requirements.
• Steam-Rated Durability: EPR seals and Class F insulation are specifically selected for high-temperature steam and hot water service.
• Normally Closed Safety: Provides an automatic fail-safe shut-off when de-energized, preventing unintended flow.
• Zero Differential Operation: Reliable shifting and sealing without the need for a minimum pressure drop.
• NEMA 1 Conduit Connection: Standard 1/2" metal conduit housing allows for straightforward integration into existing electrical runs.

What is the maximum temperature rating for the EPR seals?
In this configuration, the EPR (Ethylene Propylene) seals are rated for fluid temperatures ranging from 32°F to 295°F, ideal for low-pressure steam and hydronic heating.

Can this valve be mounted in any orientation?
While multi-poised, it is best practice to mount the valve with the solenoid in a vertical and upright position to prevent sediment accumulation in the plunger tube.

Is this valve compatible with 110V systems?
Yes, the 120Vac coil is designed to operate within standard voltage tolerances, making it compatible with 110V/120V 60Hz power supplies.
