Construction/Principle of Operation
When signal pressure enters input chamber q, the input diaphragm e is deflected left. Clearance of the nozzle y is reduced causing higher back pressure at diaphragm A u.
This diaphragm A u has larger area than diaphragm B i resulting in movement of the spool to the left. Supply pressure then flows to OUT1 q and partial exhaust from OUT2
takes place resulting in cylinder rod t movement to the right. The movement is linked via connecting rod r and feedback spring w to the input diaphragm e balancing the
higher pressure. When this occurs nozzle y clearance increases allowing centralizing of the spool o to take place. This holds the piston rod in the new position. Input signal
increase results in proportional movement of the piston rod.

25 to 300 mm
* Manufacture of strokes in 1 mm increments is possible.
Note 1) Specification values are given at normal temperature (20°C).
Note 2) Characteristics relating to accuracy differ depending on combination
with other constituent loop equipment, such as positioners and
actuators.
Note 3) Air consumption is due to exhaust from nozzle. And (ANR) indicates JIS
B0120 standard air.
