The Pneumatic Rotary Actuators for Valve Automation Handbook


You'll find lots of product or brand specific pneumatic actuator overviews or sizing checklists online. This is not one of them. Instead, we wrote this in-depth guide as an educational roadmap for understanding various styles of pneumatic rotary actuators. Our intention is to empower process operators and engineers with enough knowledge so that they can make the best choice for their specific actuation application challenges. Additionally, we provide a step-by-step guide on how to size pneumatic actuators to valves.

Here's what you'll find in this guide:

  • Overview of types of pneumatic rotary actuators and the implications they may pose for your application
  • Overview of fail-safe mechanisms and the implications they may pose for your application
  • How to reduce time and cost through streamlined valve automation sizing
  • Overview of valve-to-actuator interface and auxiliary-to-actuator interface

About Easytork Automation

Founded in 2011 and headquartered in St. Louis, Missouri, Easytork manufactures quarter turn pneumatic actuators for users worldwide in a wide variety of markets such as oil & gas, chemical, aerospace, power generation, water/municipal, general industrial, etc. Our patented spring-less internal air reservoir vane design makes our pneumatic actuator the smallest and lightest in the world. Additionally, compared to spring & diaphragm for control valves, our patented control actuator line is 1/10th the weight, 1/6th the size, significantly more cost effective and air efficient, has better than/equal to benchmark test performance, and is more robust and easier to install.

There has been no technological advancement in pneumatic actuation in over 50 years. Process users shouldn't have to cater to half century old actuation technology in order to meet their modern challenges. Easytork was founded to establish new generation of actuation innovation - our products are proudly designed with process users in mind first and foremost, improving and simplifying their process controls while generating meaningful savings and efficiencies for their facilities. Our customer service and support philosophy, much like our product, is to make our customers' lives easy by providing the highest level of attention and support.
