MB 7 + BVHM Butterfly Valve

MB 7 Assembly
$0.00 /

The MB 7 solenoid actuator serves as a drive for the BVHM butterfly valve. The assembled unit can be used for staged control of industrial installations in cold or hot air operating mode. The air volumes for low and high fire can be controlled independently.

Due to the large number of operating cycles of MB 7, the assembly is ideal for intermittent operation.

Assembled with a coupling pin and ring, the MB 7 moves the butterfly valve to the Open or Closed position. The position of the valve can be read on a valve disc position indicator on the outside of the MB 7.

In the event of a mains voltage failure, the MB 7 closes the butterfly valve. This prevents air from flowing into the furnace without being under control.

Use the selection tool on the right to pick the MB 7 and corresponding butterfly valve.
