FAQs about Automatic Actuators
As AOX, an electric valve actuator B2B manufacturer, I can provide the following answers to your questions:
1What is an electric valve actuator?
An electric valve actuator is a device that converts electrical energy into mechanical force to automate the operation of valves. It is commonly used for quarter-turn valves such as ball and butterfly valves, where it provides precise control and positioning . Electric actuators are known for their high torque output, self-braking construction, low noise level, and smooth operation over the complete valve stroke. They are particularly suitable for applications requiring high stability and constant thrust, such as in power plants or nuclear power stations .
For example, our AOX electric actuators are designed to provide reliable performance in a wide range of industrial applications, from water systems to chemical processing plants. We offer models with torque ranges from 40Nm to 4000Nm, compatible with various voltage inputs 24V DC, 24V AC, 230V AC, 400V AC.
2How to size electric butterfly valve actuators?
Sizing an electric butterfly valve actuator involves considering the following factors:
•Valve Size and Working Pressure: The required torque for valve operation depends on the valve's size and working pressure. The torque should be 1.2 to 1.5 times the maximum torque required to operate the valve . For instance, if a butterfly valve requires a torque of 100Nm, the actuator should have a torque rating of at least 120Nm to 150Nm.
•Application Requirements: Consider whether the actuator needs to be used for on-off or modulating control. Modulating actuators require more precise control and may need additional features like position feedback .
•Environmental Conditions: If the valve will be used in a harsh environment, a robust and durable design is essential. Compact designs are ideal for space-limited applications .
•Feedback and Control Options: Electric actuators can be equipped with feedback devices, solenoid valves, and other accessories to connect to automation systems. These features enhance the precision and reliability of the actuator .
For example, our NOM...H... series electric butterfly valve actuators are designed for water systems in buildings, public facilities, and urban networks. They offer both on-off and control functions, with support for 4-20mA, 0-10V, and 2-10V signals for modulating control .
3How to size electric valve actuators?
Sizing electric valve actuators generally follows similar principles to sizing electric butterfly valve actuators. Key considerations include:
•Torque Requirements: The actuator must provide sufficient torque to position the valve throughout its operating range. For example, a double-acting non-spring return actuator may be used for butterfly valves .
•Voltage and Power Supply: Ensure the actuator is compatible with the available power supply. Common voltages include 24V DC, 24V AC, 230V AC, and 400V AC .
•Environmental Protection: Enclosures should be weatherproof NEMA 4 and suitable for the operating environment. For example, our actuators are designed to withstand temperatures from -20°C to 90°C and air pressures from 0.2 to 0.8 MPa .
Mounting and Integration: The actuator should be suitable for direct-coupled mounting to the valve bonnet. Integrated control units allow for local operation without external controllers
4Hydraulic vs. Pneumatic vs. Electronic Actuators: Pros & Cons
Electric valve actuators offer precise control over valve positioning, remote operation capabilities, lower maintenance requirements, and energy efficiency. They also eliminate the need for manual operation, enhancing safety and operational efficiency in industrial processes.
