Products - Control Valves- MDM
PROPORTIONAL PRESSURE-REDUCING VALVE
MDM-5 Electrical operation

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 "EEx m II T4" and military, IP67. Adjustable valve response time.
