Reducing Valve-Induced Unplanned Downtime
Jim Cahill
Valves are the critical components in any process manufacturing and production operation that touches what is being produced. As such, they are subject to wear and tear. An ARC View report, Leveraging IIoT Technologies to Reduce Valve-Related Unplanned Downtime highlights key points from a presentation by Emerson’s Shawn Anderson at the ARC Advisory Group’s 20 th Annual Industry Forum. Here is the recap of the report…

Simplifying Pneumatic Valve Installation, Commissioning and Operation
Jim Cahill
For many applications in the process manufacturing and production industries, solenoid valves are used to “shut off, release, dose, distribute or mix fluids.” Wikipedia defines a solenoid valve as: …an electromechanically operated valve . The valve is controlled by an electric current through a solenoid : in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow…

Remotely Monitoring Storage Tank Pressure and Vacuum Relief Valves
Jim Cahill
In current times where oil supply exceeds demand, storage tanks are filling. A recent Reuters article, Oil glut up close: How Cushing copes with full crude tanks notes: There may be no better place to witness what a world awash in crude looks like, and the 9 square-mile (23.3 square km)complex seems to bear out oil traders’ fears that the industry is running out of space to contain a historic supply glut that has hammered…

Pressure Regulators in Upstream Oil and Gas Processing Applications
Jim Cahill
Managing pressures are a large part of the control strategies for upstream oil and gas applications. These pressures include those in the main processing lines, fuel lines and vapor spaces found in storage tanks. Emerson’s Thomas Weyer shared a new pressure regulator upstream oil and gas application map with me. It was designed to show the options of pressure regulators upstream and downstream of the equipment typically…

Setting Up and Calibrating Valve Positioners
Jim Cahill
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 demonstrates the setup and calibration procedure for the Fisher 3582i electro-pneumatic, single-acting positioner on a Fisher 667 Size 30 reverse-acting actuator…

Value from Monitoring Control Valves
Jim Cahill
As staff in process manufacturing and production facilities shrink due to economic or demographic conditions, on-site engineers, operations and maintenance personnel must increase their breadth of skills at the expense of skill depth. In a recent post, Monitoring Control Valves with Remote Expertise , we described how remote expertise could help augment local staff in the area of valve monitoring and maintenance. …

Online Pressure Regulator CAD Drawing Resource
Jim Cahill
For process manufacturers and producers, regulating pressure throughout the process is important for safety, efficiency and reliability. We’ve highlighted the important role of pressure regulators in numerous posts . During the front end engineering design phase of a project, having good CAD ( computer-aided design ) drawings are important in determining the best regulator for the application given piping configurations…

Monitoring Control Valves with Remote Expertise
Jim Cahill
An ARC Advisory group study highlighted that “The global process industry loses $20 billion, or five percent of annual production, due to unscheduled downtime and poor quality. ARC estimates that almost 80 percent of these losses are preventable…” Key components in controlling a process are the control valves, which directly touch the process. As such, they can be subject to corrosive, erosive and other challenging…

Separate versus Integral Final Element Accessories Questions
Jim Cahill
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 understood the whole description, But while calculating PFDavg, We will have to add the Failure rate of valve assembly (Valve+Actuator) which brings…

Positioner-Only Configuration on Digital Valve Controller
Jim Cahill
I wanted to share a quick question and answer in an email exchange in case you may have a similar question sometime down the road. The original question was: The Project is about installing two manual Fisher control valves but we want to modify it to include obtaining feedback positions back to the Control Room. ( ZSC/ZSO ). Can we configure the DVC6200 just for only positioning purposes only? If this is possible…
