GC Valves S201GF02L7DG4 Solenoid Coil

The GC Valves S201GF02L7DG4 is a normally closed solenoid valve specifically engineered for aggressive media and high-performance industrial environments. Constructed with a 316 stainless steel body, this 2-way piloted diaphragm valve features a 5/8" orifice and 1/2" NPT pipe connections, making it a reliable solution for managing flow in wash systems, water treatment, and specialized steam applications. Operating on 120Vac, the integrated Class F coil is rated for continuous duty in ambient temperatures ranging from 32°F to 125°F. The use of Viton (FKM) seal material ensures superior chemical resistance and enables the valve to handle fluid temperatures up to 230°F. This zero differential valve requires no minimum pressure to operate, allowing for consistent performance in gravity-fed or low-pressure systems. Designed for longevity and field-serviceability, the NEMA 4X conduit housing provides excellent protection against moisture and corrosion in demanding contractor environments.

Key Benefits

• 316 Stainless Steel Construction: Offers maximum corrosion resistance for acidic or slightly aggressive media.
• Zero Differential Operation: Ensures the valve opens fully without requiring line pressure, ideal for vacuum and low-flow systems.
• Viton Diaphragm: High-grade FKM seals deliver excellent thermal stability and chemical compatibility compared to standard Nitrile.
• Class F Insulation: The solenoid coil is built to withstand high internal temperatures during prolonged energized states.
• NEMA 4X Protection: Waterproof encapsulated housing allows for installation in washdown or outdoor environments.

Common Questions

Can this valve be mounted in any orientation?
While the GC Valves S201GF02L7DG4 is multi-poised, it is recommended to install it with the solenoid coil in a vertical, upright position to prevent sediment buildup in the plunger tube and ensure optimal shutoff performance.

What media is compatible with the Viton seals?
The FKM material is ideal for air, water, light oils, and many corrosive chemicals. For high-pressure steam applications, always verify that the fluid temperature does not exceed the 230°F threshold for this specific model.

How do I troubleshoot a valve that fails to open?
First, verify that the 120Vac supply matches the coil rating using a multimeter. If the electrical signal is present, check for debris in the 5/8" orifice or a restricted pilot hole, which can impede the diaphragm’s movement.
