The BIERI series WVM-6I-R position monitored poppet valves consists of directly controlled, poppet tight solenoid directional valves, suitable for high load cycles. Due 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.
Operating pressure | up to 500 bar |
Max. flow rate | 12 l/Min |
Porting | NG 6 ISO |

Directional poppet valves WVM-6I-OF
with locking mechanism
Thanks to the patented locking mechanism, these valves offer secure positioning when de-energised.
Features | Advantages |
---|---|
Direct operated, solenoid actuated | High operational safety and reliable switching |
Poppet tight | High duty cycles and long lifetime |
Position monitored with dirt resistent monitoring concept | High corrosion resistance |
An overlap area on the poppet ensures that the possible flow in the switching points near the seats is limited to a minimum | Non-contact sensors for the diagnosis in safety-relevants parts of electronic control systems |
