GC Valves S201GF02C5DG4 Solenoid Valve

The GC Valves S201GF02C5DG4 is a professional-grade, 2-way normally closed solenoid valve designed for high-reliability fluid control in industrial HVAC and water treatment systems. Built with a heavy-duty brass body and a 5/8" orifice, this piloted diaphragm valve supports a high flow coefficient (Cv) of 4.3, making it ideal for 1/2" NPT pipe connections. It features an EPR (Ethylene Propylene) seal material, providing an excellent temperature range of 32°F to 295°F for water and low-pressure steam applications. The 120Vac Coil Class F is encapsulated in a NEMA 4X waterproof conduit housing, ensuring performance in demanding environments. This zero-differential valve operates efficiently between 0 and 140 PSI (for air/water), allowing for consistent shutoff even at low pressures. For contractors, this unit offers a robust solution for automated control of aggressive media, neutral gases, and light oils.

• Broad Operating Range: Zero-differential piloted design allows for reliable opening and closing from 0 PSI up to 140 PSI.
• High-Temperature Resilience: The EPR seal material handles fluid temperatures up to 295°F, suitable for hot water and steam systems.
• Standardized Compatibility: Features 1/2 inch NPT ports and a 120V AC coil for seamless integration into existing control circuits.
• Environmental Protection: Standard NEMA 4X housing protects the internal electrical components from moisture and corrosion.
• Contractor-Focused Design: Mountable in any position with a spring-loaded plunger for positive shutoff and reduced chattering.

What media is compatible with the EPR seal in this valve?
The EPR (EPDM) seal is specifically rated for water, steam, and neutral gases. It is excellent for heat resistance but should not be used with petroleum-based oils or fluids.

Can I install this valve in any orientation?
While the S201GF02C5DG4 is multi-poised and can be mounted in any direction, veteran installers recommend a vertical, upright coil position to prevent sediment buildup in the plunger tube.

How do I resolve buzzing or chattering during operation?
Buzzing is typically caused by low voltage or debris between the plunger and the tube head. Ensure the 120V supply is stable and clean the internal plunger assembly if performance becomes sluggish.
