Example of Application
Energy and cost saving booster regulator for factory
When certain equipment requires a higher pressure than
the factory line pressure.
When the lower pressure limit for equipment must be en-
sured due to the fluctuation and reduction of the factory
line pressure.
When the actuator lacks power output for some reason but
it is not feasible to replace it with a larger bore cylinder due
to space constraints.
In spite of diverse pressure conditions of the end user,
equipment that achieves the specified high power output
must be provided.
When a small cylinder size is desired while ensuring suffi-
cient power, in order to achieve a compact drive unit.
When the hydraulic pressure of an air-hydro unit must be
raised.
When the pressure must be raised in an explosion-proof
environment.
To boost the pressure by remote operation, using an air
operated type.
