Rotary vane actuators are often used for automated pipeline valves and other critical ball and plug valve applications. This quick 2:44 YouTube video, Shafer Rotary Vane Schematic Overview, provides an overview of how these actuators work.
Emerson’s Knut Riegel joins podcast host Jim Cahill in this Emerson Automation Experts podcast to discuss motor operated valves and the information that can be extracted to improve performance.
In a recorded webinar, Smart Electric Valve Actuators for Critical Fail-Safe Applications, Emerson’s Knut Riegel and Umberto Bianchi share how these actuators are well-suited for emergency shutdown (ESD) applications.
Short videos are great ways to show how to perform an activity, such as calibrating a valve's actuator to move the valve stem based on the 4-20mA signal it receives from the control system. In this under 5-minute "how-to" video, Emerson's Alex Quah Shu Min...
One of the world's leading spots to learn about new developments in industrial valves, valve actuators and fittings is the Valve World Expo. This event was held last month in Düsseldorf, Germany. During this event, Emerson launched two new products: the Bettis EHO...
As we close in on the Emerson Exchange conference October 6-10 in Orlando, I wanted to share a problem solving story. This story is typical of what you'll find throughout the weeklong conference. Jeff Wilson, with Emerson's local business partner, Puffer-Sweiven, was...
For those non-mechanical engineers who have heard the phrase "rack and pinion" but are unfamiliar with the term, Wikipedia defines it: A rack and pinion is a type of linear actuator that comprises a pair of gears which convert rotational motion into linear motion.A...
I knew when my son went to YouTube before coming to me when he needed to learn how to tie a tie--that howto videos were valuable, easily discoverable, and broadly used. I've share examples such as How To Install Micro Motion 9739 MVD Electronic Modules on how process...
Imagine 30% of a country's energy supply relying on two safety shutdown valves to flow natural gas and liquid condensate safely from offshore oil & gas production platforms to an onshore processing facility. It's critical that the valve actuators reliably perform...
Many of the units in a refinery operate under harsh conditions. Perhaps one of the harshest is the delayed coker unit. At the time of writing this post, Wikipedia defines this unit: A delayed coker is a type of coker whose process consists of heating a residual oil...
Oil & gas production facilities and offshore platforms require the ability to periodically test the individual wells for oil, water, brine, condensate, gas, and other fluids to understand the production trends and if well operating parameter adjustments will be...
In today's guest post, Emerson's Mike McQuade shares how a mining pipeline valve application with huge torque demands necessitated a new valve actuator design to meet the challenge. Three miles above sea level in the mountains of central Peru is the Toromocho...
