In industrial automation control systems, precise control of valves and dampers is key to ensuring safe and efficient operation of processes. In situations where it is necessary to rotate ball valves, butterfly valves, plug valves, etc. by 90 degrees or more,Angular stroke electric actuatorWith its rotational output method, it has become the core device for driving and controlling in such application scenarios.

The core feature of angular actuator is that its output shaft motion is rotational motion. Usually, the output shaft undergoes precise angle control within the range of 0 ° to 90 ° (quarter turn), 0 ° to 180 °, or 0 ° to 360 °. The valve shaft is driven to rotate synchronously directly or through a connecting piece, thereby achieving the opening, closing, or adjustment of the valve. This design distinguishes it from valves that require multiple rotations to achieve opening and closing, such as gate valves.

1. Compact structure, high output torque

The angular actuator reduces the rotational motion of the motor and increases the torque through mechanisms such as worm gears or planetary gears, ultimately outputting in the form of rotation. This type of transmission has high efficiency and can generate huge output torque in a compact housing space. It is very suitable for working conditions that require a large torque to overcome the frictional force of the valve sealing surface and achieve tight shut-off, such as the control of large-diameter butterfly valves or high-pressure differential ball valves.

2. Accurate control and rapid response

Modern intelligent angular stroke actuators integrate advanced control modules that can receive switch signals or 4-20mA analog signals from the control system, accurately controlling the opening position of valves. Its rotational motion has low inertia, quick start stop, and can quickly respond to control instructions, achieving sensitive adjustment of process flow or pressure, and meeting the control requirements of high dynamic processes.

3. High integration and easy maintenance

The actuator usually comes with an integrated servo control, limit switch, torque switch, and position feedback module, making installation and debugging convenient. The sturdy shell design provides high-level outdoor and explosion-proof protection. When used for switch control, its action cycle is short, mechanical wear is relatively small, maintenance workload is low, and reliability is high.

4. Widely applicable and highly adaptable

Angular stroke actuators are ideal partners for commonly used valves in industrial fields such as ball valves, butterfly valves, and plug valves. They are widely used in various process control and cutting applications in industries such as petroleum, natural gas, chemical, water treatment, power, and metallurgy.

Angular stroke electric actuators play an important role in the field of automation control due to their powerful torque output, fast response speed, and inherent adaptability to rotary valves. It is the source of rotational power that enables reliable switching and precise adjustment.
