GC Valves S201GF02N5FG9 Solenoid Valve

The GC Valves S201GF02N5FG9 Solenoid Valve is a 2-way normally closed solenoid valve designed for veteran contractors who require zero differential performance in light industrial and HVACR applications. Engineered with a rugged brass body and a 1-inch NPT connection, this piloted diaphragm solenoid valve provides a 1-inch orifice for high-flow capacity. The integrated Class F coil is rated for 120Vac operation, delivering reliable actuation in ambient temperatures ranging from 32°F to 125°F. Equipped with a nitrile seal material, this unit is optimized for compatibility with air, water, and inert gases at fluid temperatures up to 180°F. Its zero differential design ensures the valve opens and closes reliably even without a pressure drop, making it an essential component for low-pressure systems where standard piloted valves might fail. When installing, ensure the 120V solenoid coil is positioned in a vertical, upright orientation to maintain optimal mechanical longevity and positive shutoff.

Key Benefits

• Zero Differential Operation: Ensures reliable switching even in systems with minimal to no pressure head.
• High-Flow Design: The 1-inch orifice and NPT ports allow for significant Cv ratings in liquid and gas service.
• Durable Construction: The corrosion-resistant brass body and NEMA 4/4X encapsulated coil provide protection in demanding environments.
• Media Versatility: Nitrile (Buna-N) seals offer excellent resilience against common non-corrosive fluids and oils.

Common Questions

Does this valve require a minimum pressure to operate?
No, this is a zero differential solenoid valve, meaning it can function at 0 PSI, unlike standard pilot-operated valves that require a pressure drop to lift the diaphragm.

What is the maximum fluid temperature for the nitrile seal?
The nitrile seal material in this GC Valves model is rated for fluid temperatures up to 180°F. For steam or high-temp oil applications, a Viton or EPR seal variant may be required.

Can I mount this valve in any orientation?
For maximum service life and to prevent sediment buildup in the pilot orifice, it is highly recommended to mount the valve with the coil in the vertical and upright position.
