GC Valves S302GH02N3BD5 Solenoid Valve

The GC Valves S302GH02N3BD5 Solenoid Valve is a direct acting universal solenoid valve designed for technicians who require precise fluid control in HVAC systems and industrial automation. This model is the direct updated version for S302GF02N3BD5, ensuring backward compatibility while maintaining the rugged performance expected from the S302 series. Engineered with a 1/4" NPT port and a Normally Open (NO) configuration, this valve remains open until the 120V 60Hz coil is energized. The stainless steel body provides excellent corrosion resistance, while the Buna-N (Nitrile) seals are optimized for air, water, and light oil applications within a 0-100 psi pressure range. Its 3-way operation allows for versatile piping configurations, making it a reliable choice for pneumatic control valves and pilot-operated systems. This unit is built to handle high cycle rates without compromising seal integrity in demanding commercial environments.

Key Benefits for Technicians:

• Direct Replacement: Seamlessly replaces legacy model S302GF02N3BD5 with identical mounting footprint and electrical requirements.
• Industrial Durability: The 303 stainless steel construction prevents oxidation and extends service life in high-moisture HVAC-R environments.
• Zero Differential Pressure: Operates reliably from 0 to 100 psi, eliminating the need for a minimum pressure drop to function.
• Reliable Sealing: High-grade Buna seals provide a bubble-tight shutoff against common non-corrosive fluids and gases.
• Standardized Electricals: The 120VAC solenoid coil is designed for standard commercial power supplies, simplifying field wiring.

Common Technical Questions:

What is the difference between S302GH02N3BD5 and S302GF02N3BD5?
The GH model is the current manufacturer update for the GF series, offering the same 1/4" NO 120vac specifications and physical dimensions for a direct drop-in replacement.

Can this valve be used for steam applications?
This specific configuration uses Buna-N seals, which are rated for standard fluids and temperatures; steam typically requires Ethylene Propylene (EPDM) or Viton seals. Verify your media temperature before installation.

Does this valve require a minimum operating pressure?
No, as a direct acting solenoid, it functions correctly at 0 psi and does not require a pilot pressure to actuate the plunger.
