MDM PROPORTIONAL PRESSURE-REDUCING VALVE
Electrical operation
Size 5 Series MDM-5
FEATURES
* Pressure reducing over the whole range independent of the supply pressure.
* Several sub-plates available.
* Conversion to ISO/CETOP mounting surface.
* Several control pressure ranges available.
* Different pressure ranges for the two pilot lines possible.
* Proportional solenoids with longer life for the armature in the oil.
* Several types of proportional solenoids, such as explosion proof “II 2 G EEx m II T4” and IP67.
* Adjustable valve response time.
