This valve actuator uses an air motor as the drive source.
There are two types of air motor-type actuators: All-air type and air/electric type.

This type of actuator uses an air motor for driving, a torque switch for control, and a geared limit switch, which are all pneumatic, and can be operated remotely just by supplying compressed air.
We offer two models of all-air-type actuators:

– L270 model: An actuator based on L120 model
– SMBA model: An actuator based on SMB model

• (2) SMBA model (Applicable sizes: SMBA-00, -0, -1, -2, and -3)

This type of actuator uses an air motor for driving, as well as electric control devices, such as torque switch and geared limit switch.
