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).

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?

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.
