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 ...

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling ...

Balancing valves are a critical component to ensure all our coils can reach their design flow rate when the building needs it’s maximum heating/cooling capacity. But majority of the season, our HVAC ...

On/off valves are basically on/off switches for hydraulic systems. They are typically installed in applications where precise position or speed control is not required. Proportional valves adjust flow ...

HVAC systems that regulate temperature and air quality to keep enclosed areas warm in wintertime typically depend on natural gas combustion to sustain boilers, pumps, radiators, meters, and other ...

This file type includes high resolution graphics and schematics when applicable. Today’s manufacturers routinely demand exacting precision and split-second timing from their high-speed production ...

Identify the forces that act on closure components and actuators. Describe how these forces work in the positioning of closure components. Prepare equations required to determine an actuator (i.e.

Turbine bypass valves are one of the most difficult applications in a power plant. Keeping these valves operating efficiently and avoiding unexpected failures is critical for plant operation. When ...
