Directional-control valves are vital in any pneumatic circuit, directing or blocking airflow to control the speed or sequence of operations. One method of classifying directional-control valves is by ...

ISA recently published Fluid Mechanics of Control Valves: How Valves Control Your Process by Hans D. Baumann, Ph.D., PE — a world-renowned expert on control valve technology who is credited with more ...

Bypass pipes, accompanied by a three-way control valve, are often seen in hydronic systems at both served loads (e.g., reheat coils) as well as at primary equipment (e.g., cooling towers). Reasons for ...

Before selecting an engineered solution for any fluid control application, it is crucial to understand the unique application and overall value that each ball valve provides. Ball valves come in a ...

Like so many of the core technologies integral to automated industrial operations—such as motors, drives, and I/O—valves don’t always receive the attention they deserve in the automation arena.

An oscillating control valve may appear to be the source of control instability and repair efforts are usually focused only there. When this fails to solve the issue, further investigation often ...

Speed is non-negotiable in today's automation lines, and NTA hasn't overlooked it while chasing efficiency gains. The new valves are tuned for rapid, high-frequency cycling with near-instant response, ...

Describe the forces at work tending to create instability in control valves, including inherent and installed stability. Define design improvements to improve inherent stability. Include general ...
