    When is a Safety Integrity Level Rating of a Valve Required?

    Control valves play a large role in process control. Emerson’s Riyaz Ali shared with me that he is often asked about their use in safety instrumented functions (also known as safety loops). When asked recently, he shared an ISA Safety Division newsletter from the fall of 2007. Unfortunately, I couldn’t find the newsletter in my Google searches. His article in this newsletter, When is a Safety Integrity Level (SIL)...

    How-to Video on Valve Actuator Torque Calibration

    There is nothing like a brief “how-to” video. I use these often around the home as a filter to determine if it’s something I can do myself or if I need to call out an expert. We have many examples of these in our world of process automation. Here’s one from the Emerson team managing the line of Bettis actuators. In this 4:80 YouTube video, TEC2 Model 500 Calibration with Torque Calibration Tool , Emerson’s Thomas...

    Faster Subsea Hydraulic Equipment Startups

    Offshore oil and gas producers use hydraulic power to operate much of their subsea equipment. This equipment includes valves, cylinders, motors, manifolds, blowout preventers and remote operated vehicles to name a few. Pressure regulators in Hydraulic Power Units (HPUs) help ensure the required hydraulic pressure is available for this equipment. One of the challenges in pressurizing this equipment is the time it takes...

    Butterfly Valve for Diverse Throttling and On-Off Applications

    References to the use of butterfly valves date back to James Watt, who : …made use of a butterfly valve in his steam engine, and the first Mercedes car built around 1901 introduced a butterfly valve in the fuel intake linked to the accelerator pedal. Wikipedia describes butterfly valves as from: …a family of valves called quarter-turn valves . In operation, the valve is fully open or closed when the disc is...

    Integrated Oil and Gas Well Testing

    Testing the composition of oil, gas, basic sediment and water has historically been a batch-type operation where the flow from a single well has been diverted from a header leading to the production separator over to a test separator. These components are measured in the test separator before returning for further processing. As technology has advanced to provide both subsea and topside multiphase flow metering ,...
