MB and MBF valves are of the 3-port rotary-shoe type. They are characterised for use as mixing or diverting valves, with hot or chilled water, in heating, ventilating and air conditioning applications.

The MB is driven by either the RM or XRM range of actuators or the MD10 / MD20 range of damper actuators in connection with a linkage kit. The MBF is driven by the MD20 damper actuator with appropriate linkage.

Note: The MB and MBF will operate satisfactorily as two-port valves if the bottom port is blanked off. The MB and MBF ranges of valves fitted with appropriate Schneider-Electric actuators fully comply with all relevant European directives.
