Newsletter position monitoring for directional poppet valves

Directional poppet valves with position monitoring WVM-6I-R

Bieri Hydraulik AG introduces its new directional poppet valves WVM-6I-R with position monitoring. The feature position monitoring enables the detection of the valve piston position. The electrical signals from the non-contact sensors can be used for diagnosis in safety-relevant parts of electronic control systems and in condition recording in the context of industry 4.0.

Thanks to the position monitoring, a higher diagnostic coverage (DC) of the overall system can be achieved, which enables the use in control systems of higher categories.
