21W3KB190
The ODE 21W3KB190 is a 2/2-way Normally Closed (NC), pilot-operated solenoid valve designed for high-flow applications involving water, air, and inert gases
The ODE 21W3KB190 is a 2/2-way Normally Closed (NC), pilot-operated solenoid valve designed for high-flow applications involving water, air, and inert gases. It requires a minimum differential pressure to operate.
Key Note: Unlike the direct-acting 21JN and 21TG series, the 21W3KB190 is a pilot-operated valve, so it requires at least 0.2 bar differential pressure to open properly. This design allows a much larger flow capacity of 140 L/min through the 19 mm orifice.
