Rotary Actuators

Rotary actuators, also known as quarter-turn actuators, play a vital role in industrial automation by providing rotational motion to operate various valves. They are highly versatile and compatible with different valve types like ball valves, plug valves, and butterfly valves. This versatility allows them to be used in a wide range of applications across various industries.

Benefits of Rotary / Quarter Turn Actuators:

• Precise Control: Rotary actuators deliver accurate and reliable rotational movement, ensuring optimal valve operation.
• Enhanced Efficiency: Certain models like the Habonim Compact utilize innovative technology for increased torque output while reducing air consumption. This translates to lower energy costs and reduces environmental impact.
• Wide Range of Options: ESI Technologies Group offers a comprehensive selection of rotary actuators from leading brands like Habonim, Fisher, and Ebro. This allows you to choose the perfect actuator for your specific needs and valve configuration.
• Custom Solutions: Our team can provide tailor-made solutions for demanding applications, guaranteeing optimal performance and reliability.
• Full Actuated Assembly: ESI offers complete valve actuation packages, including full assembly of actuators and valves in our dedicated service area, streamlining the procurement process.

Popular Rotary Actuator Options at ESI:

• Habonim Compact: Boasting a 7-year warranty, this innovative actuator features a 4-piston design that delivers up to double the torque of competitor 2-piston models and has a smaller footprint. This translates to reduced air consumption and lower carbon emissions.
• Fisher 2052 Diaphragm Rotary Actuator: Ideal for throttling or on-off applications on rotary-shaft valves, this compact design ensures greater mounting versatility for both skids and process plants.
• Ebro EB Actuators: Utilizing the scotch yoke principle, these actuators precisely match valve torque characteristics, resulting in a smaller size and lower air consumption. The EBRO EB-SYD covers a wide range of applications and comes in 13 sizes.

Types of Rotary Actuators

• Pneumatic Rotary Actuators:
  • Rack & Pinion: Converts linear piston motion into rotational movement for the valve stem drive. Available in single-acting and double-acting configurations.
  • Scotch Yoke: Specifically designed for butterfly valves, it offers big savings on power/air/C02 versus rack & pinion. It translates linear motion into rotational motion for reliable control. Also available in single-acting or double-acting versions.
• Electric Rotary Actuators: Convert electricity into kinetic energy for precise rotational control.

Applications for Pneumatic Actuators:

• Oil & Gas
• Food & Beverage
• Chemical Processing
• Wastewater Treatment
• Pharmaceutical
• Power Generation and more
