GC Valves S201GF02V5DG4 Solenoid Valve

The GC Valves S201GF02V5DG4 Solenoid Valve is a professional-grade, 2-way normally closed pilot-operated control solution designed for rigorous HVACR and industrial fluid handling. Constructed with a durable brass body and a 1/2" NPT connection, this unit features a 5/8" orifice providing a high flow coefficient (Cv) of 4.3. This specific model is engineered with Viton (FKM) seal material, making it highly resistant to chemical degradation and suitable for media temperatures up to 230°F, including air, inert gas, water, and light oils. The 120Vac Class F coil is housed in a NEMA 4X rated enclosure, ensuring protection against corrosion and environmental ingress in demanding mechanical rooms. With a zero-differential minimum operating pressure, this S20 Series solenoid valve maintains reliable performance even in low-pressure gravity-feed or circulating systems. Whether you are replacing a failed component or roughing in a new assembly, this valve provides the precise shut-off and chemical compatibility required by veteran contractors.

• Viton Diaphragm Assembly: Provides superior thermal and chemical resistance compared to standard nitrile, ideal for high-temperature and light oil applications.
• Zero Differential Operation: The piloted diaphragm design allows the valve to open and close reliably without requiring a minimum pressure drop.
• NEMA 4X Protection: Includes a 1/2" conduit encapsulated coil housing, offering excellent moisture and corrosion resistance for long-term field reliability.
• High Flow Capacity: The 5/8" orifice and 4.3 Cv rating ensure minimal pressure drop across the valve in high-demand fluid circuits.
• Robust Brass Construction: Heavy-duty brass body 1/2" NPT solenoid valve provides the structural integrity needed for high-cycle commercial use.

What media is compatible with the Viton seals in the S201GF02V5DG4?
The Viton (FKM) seals are specifically chosen for their compatibility with air, water, and specialized fluids like light oils or gases where standard EPDM or Nitrile might swell or fail prematurely.

Can this valve be mounted in any orientation?
While the S20 series is generally versatile, for optimal service life and to prevent sediment buildup in the pilot orifice, it is best practice to mount the valve with the solenoid in the vertical upright position.

Does this valve require pressure to cycle?
No, this model features a zero-differential design, meaning it can transition states regardless of whether there is an established pressure head in the line.
