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).

The Actuation Selection Process
A common misconception in our industry is that actuating a valve is as simple as putting the most cost-efficient actuator on top of your valve of choice, but the process is much more complicated than that.

The Critical Stem Nut: Who is Responsible for Maintenance?
One of the most important components of an automated threaded stem valve is the ubiquitous stem nut, a relatively simple and unsophisticated mechanical device that converts the rotary motion of an actuator into the linear stem movement needed to open or close one of the many types of gate valves or sluice gates.
