R750

The volume booster with transmission ratio amplifies the outlet
pressure at a 1 to 1 up to 1 to 6 ratio by a pneumatic pilot
pressure, which has no constant bleed. That signal pressure
has the same function as a spring in a common regulator.
Generating counter pressure on the diaphragm. This force is
compensated by the outlet pressure on the diaphragm's bottom side.
The ratio of pilot pressure to outlet pressure depends on the size
of the operating diaphragms.
