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

Through a large pressure range and a variety of connections this valve series covers a wide range of applications. Highly inert designs with wetted materials such as PTFE, PEEK and FFKM offer high chemical resistance.

A 2/2-way version with push-in fittings is available for this series. These connections allow PTFE or PFA hoses with an outside diameter of 2.0 mm.

This inert valve is also available as latching version (WLB series). This reduces both power consumption and heat generation to a minimum.
