5.2 Mechanical Interfaces
According to the mechanical interfaces, Ontrac electric actuators are divided into three categories:
1
、
Multi-turn:
Actuator outputs at least 360°of angular displacement and torque. If equipped with A type output shaft
can realize a linear thrust motion.
2
、
Linear:
Equipped with a linear thrust, actuator can output linear displacement and thrust, and valve stem directly
connected to the linear thrust rod.
3
、
Part-turn:
Equipped with worm gear, actuator can output 90° of angular displacement and torque. Part-turn are
divided into two categories according to their installation.
3.1 Direct mounting: Worm gearbox is connected with the flange and output shaft hole.
3.2 With base and lever: Worm gearbox is mounted on the base, and valve is drived by lever and rod.
