Valves 101 - covering the major valve types, including linear, check, quarter-turn, and pressure-relief, plus actuation basics. Valves 201 - offered for those who want to take the next step in learning more about critical flow control products, including actuators, controls, automation and more.
We begin with a broad overview of the valve industry, the major valve and actuator types, and various end-user applications. This lesson includes valve standards, basic piping information, pressure ratings and classes, as well as application issues that are critical to effective valve specification and usage. The stage is set for more detailed discussions on the major valve types to give attendees valuable knowledge that can be applied in their daily PVF work.

In this lesson, linear valve types—gate and globe valves—are explained along with stems and bonnets. In addition, there will be an in-depth look at linear valve applications.
Instructor Bio
Our check valve presenter details the unique qualities of check valves, explains how they work and why correct sizing is so essential for this valve type. Also included is a discussion of several specific check valve applications.
Instructor Bio
Pressure-relief valves (PRVs) are known as the “Last Line of Defense” in the valve industry. In this session, we learn how PRVs perform, their critical role in plant safety and important maintenance guidelines.

We continue up the valve chain to quarter-turn valves. With quarter-turn valve designs you can go from full open to full close in the blink of an eye with a mere 90-degree rotation of the closure element. This lesson will cover plug and ball valves. While these designs might seem similar, the similarities stop at 90-degree rotation. We will discuss the basic characteristics of each configuration, their pros and cons, and some of the services they are meant for.
Instructor Bio
This portion of the quarter-turn valve presentation covers three different butterfly valve designs. Like plug and ball valves, these are very simple to operate. Over the years they have become more and more popular for services no one would have thought possible less than 30 years ago. We will discuss advantages and disadvantages during this hour.
Instructor Bio
The focus of this presentation is on rotary and quarter-turn electric actuators. Their basic designs, common options and applications will be covered. The presenter will discuss electric actuators from the valve stem to the electrical connection, including mounting concerns, as well as the use of quarter-turn and multi-turn gearboxes in conjunction with electric actuation.
Instructor Bio
This lesson provides a basic understanding of the various types of fluidpower actuators that are commonly used with rotary and rising stem valves. Beginning with the basic concepts for how thrust and torque are generated, the presentation moves through power actuators that are driven from a supply of compressed air, hydraulic fluid or natural gas. Operating principles for double-acting and spring-return functions as well as failure modes are defined, along with a variety of torque generating mechanisms with their associated torque output characteristics. Attendees will see a wide range of images, animations and application photos to enhance an understanding of the lesson contents, and to provide an increased level of confidence for specifying or evaluating a variety of potential actuator solutions.
Instructor Bio
Solenoid valves are defined and explained, along with guidelines on how to make the best selection of a solenoid valve. The presenter also discusses the functions of a solenoid coil, how 2-way, 3-way and 4-way solenoids operate, and various applications for solenoid valves.
Instructor Bio
This lesson provides a basic understanding of commonly used control components to facilitate the automation of valve actuators that are driven from a supply of compressed air, hydraulic fluid or natural gas. Fluid-power actuators will generate a required thrust or torque to open and close a rotary or rising-stem valve, but some combination of control components is needed to command the actuator into action and to relay functional information back to the operator. Beginning with an overview of basic components and their schematic symbols, attendees will learn how to associate the proper combination of control components in order to achieve a desired operation. Hydraulic power units and gas-over-oil panels will also be discussed. Attendees will gain a good understanding of how to specify or evaluate valve automation control systems.
Instructor Bio
Our presenter defines control valves, explains what they do and describes typical control valve styles, including variations, types and applications. The discussion will also include valve sizing and selection, cavitation and flashing, and a brief overview of single loop controllers, control systems and pertinent safety standards.
Instructor Bio
His lesson will discuss the various control options that are used to operate and monitor electric actuators. The presenter will cover basic discrete control commands to fieldbus interfaces. Hints on specifications and where issues may arise will be discussed. Additional topics will include the asset tools available with today’s microprocessor controls, security concerns, and an introduction to Safety Integrity Level (SIL) application requirements.
