WLB Series - Diaphragm isolation solenoid valve as a latching design

Orifice diameter 1.2 - 2.0mm

WLB Valve latching


2/2-way and 3/2-way diaphragm isolation solenoid valves with fluid separation as a latching design.

A low power consumption is achieved due to the latching design and heat development - optimal for battery operated applications and liquids that react sensitively to heat transfer.
