GC Valve S401GH02S0BF5 Valve

Professional contractors and HVACR technicians rely on the GC Valve S401GH02S0BF5 for critical steam line control and high-temperature fluid management. This 1/4 inch NPT solenoid valve features a normally closed (N.C.) piloted piston design, ensuring a fail-safe shutoff until the 120V 60Hz coil is energized. Built with a rugged brass body and high-performance PTFE (Teflon) seals, it is specifically engineered to handle the rigorous demands of saturated steam applications up to 150 PSI. The direct acting pilot mechanism provides a reliable 0 PSI minimum pressure differential, making it ideal for low-pressure steam sterilization, humidification, and commercial laundry systems. With a NEMA 4X rated conduit housing, this 2-way steam valve offers superior protection against moisture and environmental contaminants. Whether you are performing a solenoid valve replacement or a new system install, this industrial-grade steam valve ensures precise flow regulation and long-term reliability in heavy-duty cycles.

Key Benefits

• Steam Rated Durability: Engineered with PTFE seals and a Class H coil to withstand high-temperature steam environments up to 366°F.
• Zero Differential Operation: The piloted piston design allows the valve to function efficiently even at 0 PSI minimum inlet pressure.
• Robust Construction: A heavy-duty brass valve body provides exceptional corrosion resistance for industrial HVACR systems.
• Environmental Protection: Features an encapsulated waterproof conduit housing (NEMA 4/4X) for safe operation in damp or wash-down areas.
• Standard Electrical Compatibility: Operates on standard 120VAC power, making it a drop-in HVACR replacement part for most North American control circuits.

Common Questions

Can the S401GH02S0BF5 be mounted in any orientation?
While this GC Valve S40 series is multi-poised, it is best practice for technicians to mount it with the solenoid coil in a vertical, upright position to prevent sediment buildup and ensure optimal piston travel.

What is the maximum pressure rating for steam service?
This specific steam solenoid valve is rated for a maximum operating pressure of 150 PSI for steam applications, ensuring safety in high-pressure boiler lines.

Are rebuild kits available for this valve?
Yes, as a veteran technician knows, the inner piston and seals can be serviced. Using a GC Valve repair kit allows for maintenance without removing the brass body from the piping.
