Users interception valves with electrical or hydraulic drive, with or without monitoring the position, the MDF3 and MCF3 valves are modular users of users, available with electrical drive (in continuous current) or hydraulic, with or without monitoring the position of the cursor (MDF3M and MCF3M versions). The MDF3 valves and the MCF3s are mounted under the directional servovals to ensure the safety of the circuit when a current interruption occurs. Versions with unloading users, closed users, cross -scheme or parallel are available. The XYZ versions with position monitoring, both initial and implemented, do not provide for auxiliary manual command and are not dismantled, to ensure the integrity of the system in critical applications.
