1. PURPOSE OF DOCUMENT
This document is prepared for showing TORK brand named electrical actuators’
installation, operation and maintenance information.
Security Notifications:
Warning: This sign Show personal and product’s security notifications. It warns
user about probably dangers. If cautions are not regarded personal injuring or
product damaged is become unavoidable.
2. PRODUCT OVERVIEW
Electrical actuators are equipment converting electrical power to mechanical power
used for valve control. Electric motor’s torque is transmitted to valve shaft through the
electrical actuator gearbox. This torque makes the valve open or close. Gearbox provides
a steady torque while turning.
The resulting motion performs the on - off function of the valve coupled to the actuator.
Depending on the feature of the coupled valve and customer request related to flow
control, it is produced as Open-Close Control Electric Actuator, Proportional Control
Electric Actuator, Battery Electric Actuator and Onsite Controlled Electric Actuator.
a. Intended Use of the Product
Electric actuators are among the most used control elements in valve control. The duties
of electric actuators can be summarized as providing the valve to open, closing the valve,
or keeping the valve in the desired opening. Electric actuators can be used in different
applications, either ON / OFF or PROPORTIONAL. Electric actuators are used to control
many valves such as ball valves, butterfly valves and plug valves.
Reasons of using electric actuators,
• Electric power is accessible.
• High output torque can be produced with low energy.
• Products have longer life.
• Products are compact and have light weight.
• Sensitive proportional control.
• High protection class.
• Wide power supply range.
• Wide turn angle range.
