Continuing Innovations in Control Valve Noise Reduction

Jim Cahill

Those that work in and around processing plants and production facilities know how loud these processes can be. As fluid flows through piping, changes in flow rates and pressures can create noise. In an Automation.com article, How Additive Manufacturing Leads to Quieter Control Valves , Emerson’s Grady Emswiler and Mike Hoyme explain how this: …sound is created by very high pressure drops across a valve, which generates…

An Alternative to Balanced Bellows in Pressure Relief Valves

Jim Cahill

Pressure relief valves (PRVs) protect pipes, manifolds, and vessels by relieving overpressure conditions. For applications that do not vent directly to atmosphere, PRV designs with metal bellows can eliminate the effects of backpressure, but these devices are prone to failures. Below is a summary of my article in the July 2023 issue of Processing, titled “ Addressing bellows failures in relief valve applications ,”…

Three Steps to Maximize Your Next Outage with a Data-Driven Valve Maintenance Strategy

Jim Cahill

Are you asking yourself why we prioritize the same valve list over and over again for every outage? When you started as a reliability or maintenance engineer, your manager handed you a list of valves to service during each outage. You’ve been using that list repeatedly at this point and you may occasionally discover that certain valves don’t require maintenance during the outage. If you are creating your own valve list…

Improve LNG Operations with Optimized Joule-Thomson Control Valves

Jim Cahill

Control valves in liquified natural gas applications must operate reliably under high pressure and cryogenic temperatures to achieve gas separation and liquefaction. This is especially true for the main cryogenic heat exchanger (MCHE), where the closely-coupled Joule-Thomson (J-T) control valves feeding the MCHE help optimize the operation of the most critical area in the entire process. My article in the Apr 2023 issue…

You just completed your outage. You are ordering pizza for the team and starting to get back to a normal shift schedule. As you’re getting back to business-as-usual, you are finishing up open items and making sure there are no issues with any of the units that were brought down for maintenance. Now, it’s been a few weeks, a month after the units are all up and running and it’s time for the post-outage review. Capturing…

Cutting Control Valve Noise

Jim Cahill

3D printing is driving innovative low noise designs. Control valve noise is created by very high pressure drops across a valve, which generate high vapor velocities as a process fluid moves through the narrowed valve body passages. Low noise trim designs have been used to address this issue, but these are costly and reduce flow capacity significantly. A new solution uses parts made with 3D alloy printing, as we explain…
