The Actuators That Drive Subsea Operations
Subsea development includes different types of activities such as exploration, drilling, completion and production.Subsea manifolds are the arrangement of piping, valves, connections, structures and the foundation used in the subsea production system to receive, combine and distribute the hydrocarbon fluid

Recommended Practices (RP) Changing Engineering and Supplying of Assemblies
The issue is that assemblies are not currently treated as “engineered” items — they are often produced by slapping the actuator on the old (or new) valve specified by the piping requirements without much understanding of the specifics of the interactions between valve and actuator connections through the drive train (coupling).

Online Control Valve Diagnostics in Today’s Cybersecurity World
The topic of cybersecurity usually brings to mind data breaches that impact financial or private information, stolen intellectual property or disruption of major events such as political elections.

Traceability
Traceability and testing of digital positioners (including the valve) is a key to process control accuracy, reliability and safety.

Solenoid Valves: Direct Acting vs. Pilot-Operated
While presenting in a recent VMA Valve Basics 101 Course in Houston, I found myself in a familiar role: explaining solenoid valves (SOVs) to attendees. (I work with solenoids so much that one VMA member at that conference joked that I needed to be wearing an I Heart Solenoids t-shirt). During the hands-on “petting zoo” portion of the program, which involves smaller groups of attendees, one of the most frequently asked questions I get from people came up: What’s the difference between direct-acting and pilot-operated SOVs, and how do we make a choice?

Essentials of Cybersecurity for Process Controls
Cybersecurity is one of the major risks facing the valve industry, and it is not a problem that can merely be solved by other parties besides the intended victim.

Inexpensive Safe Water Tapped by Correcting Control Valve Output
The error output from a control valve can come from a variety of sources: uncontrolled input pressure, uncontrolled input flow rate, inaccurate orifice size or turbulent flow through the system which causes irregularity of flow rates through the system.

The Rationale Behind Valve Characteristics
Back in the “early days,” we were taught that, to properly control flow, we should select a linear valve characteristic when the valve controls more than 25% of the piping system pressure drop at full flow.
