Description

4M (Namur) series solenoid valve with internal pilot and side plate

Product features

Internally piloted structure.
Structure in sliding column mode: good tightness and sensitive reaction.
Double control solenoid valves have memory function.
Internal hole adopts special processing technology which has little attrition friction, low start pressure and long service life.
No need to add oil for lubrication.
Install in the side plate with the surface upward, which can be used by directly connection with the actuators.
Affiliated manual devices are equipped to facilitate installation and debugging.
Several standard voltage grades are optional.
