21W7KB500-MR
The ODE 21W7KB500-MR is the largest size in the 21W pilot-operated solenoid valve series, designed for very high flow rates in water, air, and inert gas applications.
The ODE 21W7KB500-MR is the largest size in the 21W pilot-operated solenoid valve series, designed for very high flow rates in water, air, and inert gas applications.
Key Note: The 21W7KB500-MR provides the highest flow capacity in the standard 21W brass pilot-operated family. Because it is a pilot-operated valve, it requires a minimum pressure differential of 0.2 bar for reliable operation.
