WTB Series - Diaphragm isolation solenoid valve

Orifice diameter 1.2 - 2.0mm (OD)

WTB Valve PTFE Valve body
WTB Valve Flange connection
WTB Valve Flange connection


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

With a large pressure range and a variety of connection options this valve series covers a wide range of areas of application. Highly inert designs with wetted materials such as PTFE, PEEK and FFKM offer high chemical resistance.

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