Operating speed
The operating duration can be calculated from the oil displacement of the actuator. The LPU can
deliver a flow, smoothly manually adjusted from 250 to 1000 ml/min at 50 Hz.
Example
A BRC 250 can be opened in:
minimum 50 ml / 1000 ml x 60 sec. = 3.0 sec.
maximum 50 ml / 250 ml x 60 sec. = 12.0 sec.
For adjustment please refer to instruction.
