Sample Transcript

Throttling valves are used to regulate the amount of fluid that passes through the valve. Like an on/off valve, a throttling valve can be fully open to allow maximum flow or fully closed to stop flow. But a throttling valve can also be partially open to let some of the fluid pass through. Throttling valves can be used to control downstream conditions including the flow rate, pressure, or temperature.

Valve Basics FAQs

What is a valve designed to do?
A valve is used to control or regulate the flow of gas or fluids through a pipeline

What are valves made of?
Valves are typically made of the same material as the pipes they are attached to. Commonly these are carbon steel, stainless steel, or chrome-molybdenum steel.

What is a face-to-face dimension?
the face-to-face dimension is the distance between the surfaces of the valve body that contact and connect to the downstream and upstream piping.

What are some common types of valve connections?
Valve ports can connect to the piping in a number of ways, including: threaded connections, flanged connections, and welded end connections.

How is pipe pressure measured?
In the United states, the pressure that a pipe can safely carry is generally measured in pounds per square inch. Outside of the U.S., pressure is measured in bars and reported as nominal pressure (PN).
