Manual actuators consist of three types: the lock lever, the worm gear and the center handle type.
The design depends on the model of valve that it will be used with.

Lock lever type

Opening and closing operations are
conducted by merely turning the lever 90
degrees. The 10-stage locking mechanism
allows flow rate control.

Worm gear type

The worm wheel works as a gear reducer to
greatly reduce the torque required for
extremely light open and close operations.
The valve opening angle can be set as
desired for completely stepless control of the
flow rate.

Center handle type

The planetary gear works as a gear reducer
to greatly reduce the torque required for
extremely light open and close operations.
The valve opening angle can be set as
desired for completely stepless control of the
flow rate.
