GC Valve S311GF02N9BF5 Solenoid Valve

The GC Valve S311GF02N9BF5 is a high-performance 2-way normally closed solenoid valve designed for precision fluid control in industrial and commercial HVACR applications. Built with a rugged forged brass body and 1/4" NPT ports, this valve features a 3/8" orifice, providing a high flow coefficient (Cv) relative to its compact footprint. The unit is equipped with a 120Vac Class F coil, ensuring reliable actuation and thermal stability under continuous duty cycles. Utilizing Nitrile (NBR) seal material, it offers excellent chemical compatibility for air, water, and inert gas service, maintaining a tight shut-off in pressures ranging from 0 to 150 PSI depending on the media. This direct-acting solenoid is a standard replacement for many automated process systems, offering low power consumption and rapid response times for critical flow management.

• Robust Construction: The forged brass housing provides superior pressure ratings and corrosion resistance compared to cast alternatives.
• High-Temperature Insulation: The Class F coil rating allows for reliable operation in elevated ambient environments without premature electrical failure.
• Nitrile Seal Versatility: Optimized for standard fluid applications, ensuring bubble-tight sealing and long-term durability against mechanical wear.
• Standardized Integration: The 1/4" NPT connection and 120V configuration allow for seamless drop-in installation in existing control circuits.

Common Technical Questions

What is the maximum operating pressure differential for the S311GF02N9BF5?
This valve is designed to operate effectively starting from 0 PSI (direct-acting) up to its maximum rated utility pressure, typically used for air and water applications up to 150 PSI.

Can this GC Valve solenoid be mounted in any orientation?
For optimal service life and to prevent sediment buildup in the armature tube, it is recommended to install the valve with the solenoid coil in the upright vertical position, though it can function in other orientations if necessary.

Is the coil compatible with outdoor installations?
While the Class F coil handles heat well, ensure the lead wires and electrical connections are housed in a NEMA-rated enclosure if the unit is exposed to moisture or direct weather elements.
