    Blog: IIoT in Steps for Monitoring Valve Health

    Manufacturers and producers can improve safety, reliability and efficiency by applying additional sensors, analytics and experts. Difficulties in installation have held back these improvements, but the Industrial Internet of Things (IIoT) technologies have significantly reduced these barriers. One example of IIoT in action is featured in a Valve magazine article, Monitoring Valve Health via the Internet . Emerson’s...

    Blog: Low-Bleed or Standard Relays for Control Valves?

    Happy New Year everyone! I hope your holidays helped to recharge your batteries and get you off to a great start for 2018. I saw this exchange in my email over the holidays about the effects of using low-bleed relays with Fisher DVC6200 digital valve controllers for control applications as compared to standard relays. This question was in response to a blog post from many years ago, Positioner Pneumatic Pressure Bleed...

    Blog: Improving Valve Total Cost of Ownership

    An important metric for driving continuous improvement in the process industries is total cost of ownership (TCO). One of the methods to lower these costs is to standardize and limit variations on the plant equipment across sites and geographic locations. In a Flow Control magazine article, Improve Total Cost of Ownership with Valves , Emerson’s Christof Lindner shares ways that standardizing equipment, suppliers...
