OVERVIEW
The Multismotor is a pneumatic actuator of
multi-spring type structure. It accepts the pneumatic output of positioners or other control
equipments, converts the pneumatic force into a
mechanical force with the diaphragm, and let the
diaphragm force balanced with the spring force,
there by setting the valve position. The Multismotor, which employ multiple springs and a
high air supply pressure, are much more compact and light as compared with conventional
actuators.

1) Direct action
As the air pressure fed to the top chamber of the diaphragm case increases, the actuator stem moves
downward.
2) Reverse action
As the air pressure fed to the bottom chamber of the
diaphragm case increases, the actuator stem moves
upward.
Optional accessories
Positioner*, pressure regulator with filter, hand wheel*,
limit switch, solenoid valve, motion transmitter, booster
relay, lock-up valve, and others.
Note)1) For the optional items, refer to the specification
sheets and installation drawing of respective
accessories.
