GC Valves S201GF02N5DG4 Solenoid Valve

The GC Valves S201GF02N5DG4 Solenoid Valve is a 2-way, normally closed piloted diaphragm valve designed for professional-grade fluid control. Built with a rugged brass body and high-performance Nitrile (NBR) seals, this unit is a reliable choice for handling air, water, inert gases, and light oils. It features a 1/2" NPT connection and a substantial 5/8" orifice, providing a high flow coefficient (Cv) of 4.3. The 120Vac Class F coil is rated for continuous duty in temperatures up to 180°F, making it suitable for demanding commercial and industrial environments. As a zero differential capable valve, it operates effectively even at 0 PSI, ensuring consistent performance in low-pressure systems. Technicians rely on the S20 series for its NEMA 4X rated encapsulation, which protects the electrical housing from moisture and corrosion in the field.

• Zero Pressure Differential: Operating range from 0 to 140 PSI (AC) allows for reliable switching in both gravity-fed and high-pressure lines.
• Broad Media Compatibility: The Nitrile seal material and brass construction provide excellent resistance when used with water, air, and neutral gases.
• Efficient Flow Rates: A 5/8" orifice delivers a 4.3 Cv rating, minimizing pressure drop across the 1/2" NPT ports.
• Industrial Durability: The Class F insulation and NEMA 4X conduit housing ensure the 120V coil withstands harsh environment cycling.

Can this valve be mounted in any orientation?
While these valves are multi-poised, it is standard practice to install the solenoid in a vertical, upright position to prevent sediment buildup in the plunger tube and ensure the longest possible service life.

What causes a humming or chattering noise during operation?
In most HVACR applications, buzzing is typically caused by low voltage to the coil or debris trapped between the plunger and the tube head. Ensure the 120Vac supply is stable and install a fine mesh strainer upstream if the media contains particulates.

Is this valve compatible with steam applications?
No, the Nitrile seals in the S201GF02N5DG4 are rated for a maximum fluid temperature of 180°F. For steam service, a valve with EPDM or Viton seals and a Class H coil is required.
