GC Valve S401GH02S0DF5 Valve

The GC Valve S401GH02S0DF5 is a high-performance 2-way piloted piston solenoid valve specifically engineered for demanding steam flow control in industrial and commercial HVACR systems. This normally closed (N/C) valve features a 1/2" NPT connection and is built with a rugged brass body to withstand high-temperature environments. Rated for 0 to 150 PSI steam pressure, the S401GH02S0DF5 utilizes a Class H coil designed for continuous duty at 120V AC. The integration of Teflon (PTFE) seals ensures a reliable, bubble-tight shut-off and long-term chemical resistance against steam-induced degradation. Designed for veteran technicians, this valve provides a 3/8" orifice for optimal flow capacity and is a direct-fit solution for steam distribution manifolds, heat exchangers, and boiler feed systems. By maintaining precise pressure regulation, this 120V solenoid valve prevents system over-pressurization, ensuring stable thermal performance and operational efficiency across the entire steam loop.

• Steam-Rated Durability: Specifically designed to handle 150 PSI steam applications without diaphragm fatigue.
• High-Temperature Resilience: Equipped with a Class H insulated coil and Teflon seals to manage extreme thermal loads.
• Reliable Fail-Safe: The normally closed configuration ensures the valve remains sealed during power loss for system safety.
• Optimized Flow: Features a 3/8" orifice within a 1/2" NPT housing to balance high Cv requirements with compact installation.
• Standardized Voltage: Operates on a standard 120V 60Hz signal, simplifying field replacement in existing control circuits.

What is the maximum temperature rating for the GC Valve S401GH02S0DF5?
This valve is optimized for steam service up to 150 PSI, which corresponds to saturated steam temperatures of approximately 366°F, supported by its high-temp Teflon seals and Class H coil insulation.

Can this solenoid valve be mounted in any orientation?
While the S40 series is generally versatile, it is highly recommended to install the valve with the solenoid in the upright vertical position to prevent sediment buildup and ensure the longevity of the piloted piston assembly.

Is the S401GH02S0DF5 suitable for water or air service?
Yes, although specifically optimized for steam, its brass construction and PTFE seals allow it to handle pressurized air, inert gases, and water, provided the pressure differential remains within the 0 to 150 PSI range.
