2" 2-Way Normally Closed Piloted Diaphragm Solenoid Valve (120V)
GC Valves S211YF02N5JJ2 2" 2-way, normally closed (N.C.), pilot-operated diaphragm valve
Manage large-volume fluid and gas routing with the heavy-duty GC Valves S211YF02N5JJ2 solenoid valve. Part of the high-performance S211 series, this 2-way, normally closed (N.C.), pilot-operated diaphragm valve is engineered to handle substantial flow demands. It features an oversized 2" Female NPT inlet and outlet port structure matched with a 1-1/4" internal orifice, allowing for an exceptional flow coefficient that prevents system bottlenecks.
Equipped with a premium Nitrile (NBR) diaphragm assembly and a rugged forged brass body, this valve is highly resilient against wear from air, water, inert gases, and light oils. Driven by an energy-efficient Class F 110V/120V AC coil paired with a standard DIN plug-in electrical housing, it offers snappy, zero-leak fluid power control for demanding commercial wash arrays, water treatment loops, and industrial plumbing systems.
Key features and benefits include:
- Massive Volumetric Delivery: The large 2" pipe connection and 1-1/4" interior orifice ensure high-velocity, high-volume fluid distribution with minimal pressure drop.
- Pilot-Operated Efficiency: Uses the inherent pressure of the fluid line to assist in lifting the large diaphragm, minimizing electrical power consumption while maintaining a stable hold.
- Standardized DIN Electrical Housing: Form factor utilizes a plug-in DIN connector configuration, accelerating initial wiring installation and making field diagnostic coil replacement a breeze.

- Eliminates Line Bottlenecks: Delivers an exceptional flow coefficient of 28, moving massive volumes of water or compressed air with minimal pressure drop, making it perfect for main manifold water loops and heavy rinse arrays.
- Pressure-Assisted Switching: Uses the upstream line pressure to help lift the main diaphragm off its seat. This design achieves high flow capacities while keeping electrical power demand remarkably low.
- Positive Drop-Tight Sealing: Leverages system fluid pressure to tightly hold the valve closed when de-energized, ensuring zero-leak performance even under maximum line pressure.
- Simplified Field Electrical Setup: Uses an industry-standard multi-pin DIN plug-in connector housing. It streamlines layout designs by eliminating messy external pigtail wire splices.
- Scale-Resistant Body: Heavy-duty forged brass housing prevents internal mineral scale accumulation and easily withstands harsh physical impacts, line vibration, and high-pressure fluid environments.
