MLV Series - Isolated solenoid valve

Orifice diameter 2,5mm (OD)

MLV Series Valves
MLV 2-way valve


2/2-way and 3/2-way diaphragm isolation solenoid valves with fluid separation.

With a nominal width of 2.5 mm this valve enables significantly higher flow rates than the standard MTV, WTA and WTB series and is still extremely compact, compared to the diaphragm solenoid valves with high flow rates and a nominal diameter of 4.0 to 6.0 mm.
