GC Valves S211GH02K4DG1 Solenoid Valve

The GC Valves S211GH02K4DG1 Solenoid Valve is a robust, normally closed (N/C) 2-way pilot-operated valve designed for professional technicians managing high-temperature fluid and gas control. This unit serves as the direct S211GH02K4DG1 replacement for the older S211GF model, featuring a standard high-temperature coil rated for continuous duty up to 230°F. Built with a 1/2" NPT connection and a durable brass body, it handles 120V AC power requirements with a 250 PSI maximum operating pressure differential. Whether you are servicing HVAC solenoid valve systems or industrial steam and water lines, this valve provides reliable shut-off for air, inert gases, water, and light oils. The inclusion of the high-temp solenoid coil as a standard feature ensures system stability in demanding boiler rooms or commercial laundry environments where thermal cycling is frequent. For contractors seeking a 1/2" N/C 120V valve that balances flow capacity with high-pressure resilience, this GC Valves assembly is the industry standard for industrial solenoid valve applications.

Technical Benefits for Contractors:

• Enhanced Thermal Limits: The integrated high-temperature coil allows for safe operation in ambient and fluid temperatures up to 230°F, preventing premature coil burnout.
• Superior Pressure Handling: Rated for up to 250 PSI, making it suitable for high-pressure water and air systems where standard valves fail.
• Direct Retrofit Compatibility: Engineered as the updated S211GF02K4DG1 equivalent, ensuring seamless drop-in replacement without piping modifications.
• Reliable N/C Operation: The normally closed solenoid valve configuration ensures safety by automatically closing the orifice upon loss of power.
• Versatile Media Compatibility: High-grade internal components are optimized for air, water, and oil control, reducing the need to stock multiple specialized valves.

Common Technical Questions:

Can this valve be mounted in any orientation?
For optimal service life and to prevent sediment buildup in the pilot orifice, it is recommended to mount the solenoid in the upright vertical position; however, it is designed to function in various orientations if line conditions are clean.

What is the difference between the S211GH and the S211GF series?
The "H" designation in the GC Valves S211GH02K4DG1 indicates that the high-temperature coil is included as a standard specification, whereas the "F" series utilized a lower-rated insulation class.

Is this valve suitable for steam applications?
Yes, given the 230°F temperature rating and the 250 PSI pressure limit, this valve is frequently utilized in low-pressure steam and hot water circulation loops.
