Jul. 12, 2021

Gas taps are the backbone of most laboratories and play a central role in daily operations. But even though they are so common in these environments, it is not common knowledge how they work, what they are specifically used for, and what gases they are suitable for.

Therefore, the laboratory valve supplier will answer all your gas tap questions in one helpful post.

What is a gas tap?

A laboratory gas tap or laboratory gas valve is a device that controls the flow of gas from its source of supply through a pipe.

They are essential devices in a range of chemical and physical exercises, from the basic level all the way up to commercial, industrial or research laboratories. They are usually located on a laboratory bench where they can be easily accessed by students, scientists or laboratory technicians.

How do gas taps work?

Gas faucets work very similar to faucets in that the valve blocks the free flow of gas until the faucet is turned and the valve is opened. Different faucets have different types of valves. An example of this is the push-turn valve or needle valve used in a drop lever faucet.

Gas Faucet Applications

Gas valves are used to control the flow of various gases in laboratory applications. The most common are natural gas and liquefied petroleum gas. Gas taps suitable for most pressurized gases in this environment are available.

Why are gas faucets yellow?

Gas tap controls are often bright yellow in school laboratory environments where they need to be easily visible and error free for safety reasons. The yellow pull-down lever, used for a series of gas faucets, allows teachers to quickly scan the room and determine if the faucet is turned on.

However, in commercial and scientific laboratories, the handwheels on laboratory gas taps can be color coded according to the standards set out in DIN EN 13792 for easy reference
