FAQs: Frequently asked Questions

Following questions have been answered in detail in the course:

What are valves?

Pipe valves are a type of pipe fitting designed to control the flow of fluid through a pipeline.

What is the type of valves?

Isolation Valves: Ball, butterfly, diaphragm, gate, pinch, piston, and plug valves. Regulation Valves: Ball, butterfly, diaphragm, globe, needle, pinch, and plug valves.

Safety Relief Valves: Pressure release and vacuum relief valves.

Non-Return Valves: Swing check and lift check valves.

How do I know which valve to use?

The fluid flow rate and the flow velocity. Flow rate and nominal speed are essential elements that will help you choose the appropriate valve, especially if it is to be used to regulate this flow rate.

What are the uses of valves?

Valves have many uses, including controlling water for irrigation, industrial uses for controlling processes, residential uses such as on/off and pressure control to dish and clothes washers and taps in the home.

What is the most commonly used valve type?

Quarter-turn 2-way ball valves are by far the most common type of process control valve. They are 2-way (inlet and outlet), 2-position (open and closed) valves that are used for shut-off or isolation of a system, or a loop or component within a system.

Why is gate valve used?

A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline.

What is the difference between PSV and PRV?

While the term PRV is sometimes used interchangeably with PSV, there is a difference between the two. A PRV opens gradually in relation to the pressure, while a PSV is opened suddenly once the pressure hits a certain level in order to avoid over-pressurization and a potential process safety incident.

How do I choose a valve size?

When sizing a control valve, the rule of thumb is to size it so that it operates somewhere between 20-80% open at maximum required flow rate and whenever possible, not much less than 20% open at the minimum required flow rate.

What does API 600 mean?

API Standard 600, from the American Petroleum Institute, describes the criteria for valve design/construction and the material/trim designations for steel gate valves. The most recent version of this standard was published in January 2015, effective as of July 15, 2015.

What is API 6D valves?

API 6D covers the design, manufacture, testing, and documentation for pipeline ball, check, gate, and plug valves for pressure ratings up to ASME class 2500.

What is the duration of course

Total duration of the course is 1 hour. However, it is recommended to watch the lecture at least thrice, so that the fundamentals covered can be easily grabbed.
