Overview

The are many different classes of service that control valves are present in, including general service, medium service and severe service.

In Industrial applications, severe service conditions often presents challenges that other services do not. These conditions include flashing, cavitation, flow, actuation, shutoff, slurries and service/repair. Our objective is to explore several of these challenges along with potential solutions.

Attendees will learn the causes and effects of flashing and cavitation in control valves as well as solutions for reducing their effects. Other key topics include the challenges of delivering the proper flow for applications, the best solutions for providing flow, the variety of actuation available for control valves, the effects of slurries in control valves as well as solutions for reducing its effects, and preventative maintenance needs in severe service applications.

Key Takeaways

  • Learn the fundamentals of flashing and cavitation
  • Understand how applying the Bernoulli principle can reduce damaging effects of cavitation
  • Understand the difference between force seated and position seated control valve designs
  • Understand the damaging effects slurries can have on control valves and how to reduce their impact
