Variable for Any Requirement

The key performance indicators for angle/inline valves are reliability and variability. The 21.4 Mini Angle/Inline Valve series combines both. Tested in thousands of demanding applications under various process conditions the 21.4 series has proven its outstanding reliability. With its electromagnetic actuator, it’s especially suited for sealing and venting requirements in applications with no access to compressed air. It’s available in angle or inline design and comes with a wide range of accessories of flange connectors and adapters to fit nearly every requirement.


Based on a reliable and robust core design the 21.4 Mini Angle/Inline Valve is available in DN 5 with ISO-KF flange and adapters for DN 4, 8, 10 as well as pipe connectors for OD ¼" and OD 6. The electromagnetic actuator is laid out for two million cycles.
