Outline

This valve actuator uses an air motor as the drive source.
There are two types of air motor-driven actuators:

1. All-air type

2. Air/electric type

All-air Type

This actuator is fully pneumatic, utilizing:
– Air motor for driving.
– Pneumatic torque switch for control.
– Pneumatic geared limit switch.

With this design, it can be operated remotely simply by supplying compressed air.

Models available:
– L270 model: Based on the L120 model.
– SMBA model: Based on the SMB model.
• Applicable sizes: SMBA-00, -0, -1, -2, and -3.

Air/Electric Type

This actuator uses an air motor for driving, while control devices such as torque switch and geared limit switch are electric.
This hybrid design combines the driving power of compressed air with the precision of electrical control.
