Avoiding Actuator Damage from Failed Components
Riyaz Ali discussed with a major international oil company ways to eliminate supply line relief valves or needs for higher pressure-rated actuators should the air filter regulator (AFR) fail.
When is a SIL Suitability Rating Required for Final Control Elements?
Riyaz Ali provides clarity on when to assign the SIL suitability for valves used in different scenarios (process control vs. safety shutdown) and establish criteria to assign SIL applicability for the “Final Element”.
Approaches to Partial Stroke Testing Safety Valves
The safety valve within a safety instrumented function (SIF) must be tested regularly to help assure proper operation in the event of a safety demand. Operators usually perform an offline full stroke test during a scheduled shutdown because of the impact of this test...
Safety Shutdown Valve Local Control Panel
For process manufacturers and producers with safety shutdown applications, local control panels are often installed to provide visibility and control actions to operators locally out in the process area. Actions can be taken at these panels to initiate an emergency...
Testing Valves in Safety Instrumented Functions
Safety instrumented systems are a critical part of process manufacturers and producers overall process safety management in protecting personnel, environment, equipment, property, reputation and image. In an Offshore Engineer article, Safety Instrumented Function loop...
Separate versus Integral Final Element Accessories Questions
A post from a few years ago, Separate Versus Integral Final Element Accessories in Safety Applications, continues to generate some good questions. I thought I'd make these questions and associated answers more visible in today's post. Here's the first question: I...
Safety Instrumented System Solenoid-Operated Valve Approaches
Last week at the Emerson Exchange conference, I caught up with Emerson's Riyaz Ali. You may recall Riyaz from many safety instrumented system-related posts. We discussed some of the trends in integrated positioners + solenoid valves + limit switches + valve position...
Safety Valve Positioners and Common Cause Failure Questions
If you work with pumps in your facility, you may be familiar with the Empowering Pumps site, a wealth of information to help you with these important assets in your plant. Founder Charli K. Matthews has launched something similar for valves, Empowering Valves. I had...
Separate Versus Integral Final Element Accessories in Safety Applications
Final elements such as safety shutdown valves, emergency isolation valves, blowdown valves, etc., in safety instrumented functions (SIFs) are equipped with various accessories such as digital valve controllers, solenoid valves (SOV), and volume boosters, to name a...
