How Does Our Spring-less Actuator Work?

Air reservoir tanks are commonly used to emergency shutdown (ESD) mission critical valves that would otherwise be too large with springs. Easytork’s quarter turn pneumatic valve actuators utilize an internal air reservoir to ensure valve closure, improving on the way springs in a spring return actuator do. When there is air failure, the pressurized air stored in the reservoir is released to drive the actuator to its fail position.

About Easytork

Headquartered in St. Louis, Missouri, Easytork manufactures quarter turn pneumatic rotary valve 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 most compact, efficient, and accurate in the world for isolation valves and for modulation control valves.

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. We were founded to establish a better generation of actuation - our products are designed with process users in mind first and foremost, improving and simplifying their process controls while maximizing 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. Easytork is ISO 9001:2015 certified.
