6.3

Orifice Installment

Hunting can be occurred when the actuator

’s volume is too small. In order to prevent hunting, orifice

can be used.

6.3.1

Plate type Orifice Installment

By installing the plate type orifice, the flow rate

of the supply pressure to actuator can be

reduced. The diameter of orifice hole is 1 mm.
