GC Valves S201GH02C5DG4 Solenoid Valve

The GC Valves S201GH02C5DG4 is a normally closed solenoid valve designed for high-performance fluid control in industrial and HVACR environments. Engineered with a durable brass body and 1/2" NPT connections, this 2-way piloted diaphragm valve supports zero-differential operation, making it ideal for low-pressure steam applications. The internal EPR (Ethylene Propylene Rubber) seal material ensures chemical compatibility with steam and water, while the 5/8" orifice allows for a high flow coefficient (Cv) to maintain system efficiency. To handle the thermal demands of steam lines up to 50 PSI at 297°F, this valve utilizes a 120V AC solenoid coil with a Class H insulation rating. Technicians frequently spec the S201GH02C5DG4 for its reliability in steam solenoid valve applications where a secure, leaktight seal is critical for safety and process regulation.

Key Benefits:

• High-Temperature Durability: The Class H coil and EPR seals are specifically rated for steam and hot water applications.
• Zero Differential Operation: Operates reliably without requiring a minimum pressure drop across the valve.
• Robust Construction: Precision-machined brass body and stainless steel internal components prevent premature wear in harsh environments.
• Standardized Integration: The 1/2" NPT pipe size and 120V AC voltage cater to standard industrial piping and electrical specifications.

Common Questions:

Can the S201GH02C5DG4 be used for potable water?
No, this specific model is designed for steam and non-potable water applications. It is not lead-free or NSF-61 certified for human consumption.

What is the maximum pressure rating for steam?
This valve is rated for steam pressures up to 50 PSI. Exceeding this limit can cause diaphragm failure or improper seating.

Does this valve require a minimum pressure to open?
The S20 series utilizes a zero-differential design, meaning it will open and close even if there is no pressure difference between the inlet and outlet ports.
