Quarter Turn Actuators
General Guide & Overview
These actuators are the driving force behind quarter turn valve actuators, which are used to control the flow of various fluids in industrial processes. Quarter turn actuators specifically work by rotating the valve stem a quarter of a full rotation, opening or closing the valve.
Understanding the terminology associated with quarter turn actuators is essential. Terms such as quarter-turn, position, CW (clockwise) rotation, CCW (counterclockwise) rotation, stroke, cycle, and safety factor will be discussed in detail to ensure a full understanding of their functionalities and implications.
When it comes to selecting the right quarter turn actuator, we will specifically focus on Bettis actuators. Sizing Bettis actuators involves obtaining the maximum torque requirement and identifying the type of actuator required. We will guide you through the specific sizing information for Bettis rack and pinion, double-acting actuators, and spring-return actuators.
Types of Electric Actuators for Valves
Electric actuators are essential devices that utilize power to drive valves, enabling automated and remote control over valve operations. These actuators come in various types based on their modes of operation, including manual, pneumatic, hydraulic, and electric.
This section delves into the working principle, components, and types of electric actuators specifically used for valves. It explores the process of converting electrical energy into mechanical energy through an electric motor and the subsequent transmission of rotational motion to the valve stem via gears. Limit switches are incorporated to precisely control the valve's position.
Within the realm of electric actuators, three prominent types deserve attention: multi-turn electric actuators, linear output electric actuators, and 1/4 turn electric actuators. Each type presents distinct advantages and is uniquely suitable for various valve applications.
Selection and Application of Electric Actuators
In order to ensure the smooth operation and optimal performance of valves, it is crucial to select the appropriate electric actuators that suit the specific valve applications. The selection process involves considering various factors to ensure a perfect match between the electric actuator and the valve's working conditions.
One of the key considerations is the required output torque or displacement thrust. The electric actuator must be capable of generating sufficient power to operate the valve effectively. Additionally, factors such as the type of actuator (control or on/off type), the frequency of valve use, and the power requirements must also be taken into account during the selection process.
It is equally important to choose a reliable brand for electric actuators to ensure their durability and longevity. Reliability is crucial in industrial processes as it minimizes downtime and maintenance costs. By selecting high-quality electric actuators, users can enhance the safety and environmental protection measures within their operations.
The role of electric actuators goes beyond mere valve control. They play a significant role in optimizing the efficiency of power plants and other automated systems. The correct selection of electric actuators ensures the reliability, safety, and efficiency of these systems, leading to improved overall performance and reduced downtime.
The selection process involves considering factors such as the required output torque, valve use frequency, and power requirements. It is crucial to match the right actuator to the valve's working conditions to ensure optimal performance and efficiency.
