Elveflow Solenoid 2-way valve

Elveflow Microfluidic Solenoid Valve 

Discontinued 2-Port/2-Position Valve for Microfluidic Flow Switching

The MFV-NP-22-NO_2 is a legacy Elveflow microfluidic solenoid valve designed for low-pressure applications requiring fast and precise flow control. This 2-port/2-position (2/2) valve operates in a normally open (NO) configuration and was commonly used for stop-and-go flow switching, liquid sampling, and sequential injection in microfluidic systems when paired with a compatible valve controller.

Although this model has been retired and replaced by Elveflow’s V3 “smart” valve series, it remains referenced in archived product catalogs and is still compatible with MUX wire valve controllers (V2 and V3), provided a USB-C to micro-USB adapter is used.
