Quarter Turn Actuator Suppliers

A quarter turn actuator is a type of actuator that rotates a valve or other mechanical device by 90 degrees, or a quarter turn. It is commonly used in industrial applications to control the flow of fluids or gases. Quarter turn actuators can be electric, pneumatic, or hydraulic, and are designed to provide precise and reliable operation. They are often used in conjunction with other control systems to automate processes and improve efficiency.

Quarter turn actuators are used to rotate a valve or a damper by 90 degrees. There are different types of quarter turn actuators available in the market, including:

• Electric actuators: These actuators use an electric motor to rotate the valve or damper.
• Pneumatic actuators: These actuators use compressed air to rotate the valve or damper.
• Hydraulic actuators: These actuators use hydraulic fluid to rotate the valve or damper.
• Manual actuators: These actuators are operated manually by turning a handwheel or lever.
• Spring return actuators: These actuators use a spring to return the valve or damper to its original position when the power is turned off.
• Double acting actuators: These actuators use air or hydraulic pressure to rotate the valve or damper in both directions.
• Rack and pinion actuators: These actuators use a gear mechanism to rotate the valve or damper.
• Scotch yoke actuators: These actuators use a yoke mechanism to convert linear motion into rotational motion.

Worm gear actuators: These actuators use a worm gear mechanism to rotate the valve or damper.

When buying a quarter turn actuator, some key features to consider include the torque output, speed, power supply requirements, control options, and environmental factors such as temperature and moisture. It is also important to consider the type of valve or equipment the actuator will be used with and ensure compatibility. Additionally, factors such as reliability, durability, and ease of maintenance should be taken into account.

The maximum torque capacity of a quarter turn actuator can vary depending on factors such as the size and type of actuator, the application, and the manufacturer's specifications. It is best to consult the product documentation or contact the manufacturer for specific information.

However, in general, the operating temperature range of a quarter turn actuator can vary depending on the materials used in its construction and the intended application. Some quarter turn actuators are designed to operate in temperatures ranging from -40°C to +120°C, while others can withstand extreme temperatures up to 200°C or higher. It is important to consult the manufacturer's specifications for the specific quarter turn actuator in question to determine its operating temperature range.

The IP rating of a quarter turn actuator depends on the specific model and manufacturer. However, most quarter turn actuators have an IP rating of at least IP65, which means they are protected against dust and water jets. Some models may have higher IP ratings, such as IP67 or IP68, which offer even greater protection against dust and water immersion. It is important to check the specifications of the specific quarter turn actuator to determine its IP rating.

However, the expected lifespan of a quarter turn actuator can vary depending on several factors such as the quality of the materials used, the frequency of use, the operating conditions, and the maintenance practices. Generally, a well-maintained quarter turn actuator can last for several years, while a poorly maintained one may fail prematurely. It is recommended to follow the manufacturer's guidelines for maintenance and replacement to ensure the longevity of the actuator.

The installation process for a quarter turn actuator involves several steps. First, the actuator must be mounted securely onto the valve stem or shaft using the appropriate mounting bracket. The actuator's wiring must then be connected to the control system or power supply. Once the actuator is mounted and wired, it must be calibrated to ensure that it is operating correctly and responding to the control system's commands. Finally, the actuator's torque output must be adjusted to match the valve's requirements, ensuring that it can open and close the valve effectively.

The warranty period for a quarter turn actuator may vary depending on the manufacturer, model, and other factors. It is best to check the product specifications or contact the manufacturer for more information.
