The Common Types of Valves Every Gas and Oil Engineer Should Know About

What do you know about valve in every gas and oil industry? Most of the oil and gas engineers must know it in order to determine the right type of valve for this industry. Valve is an installed device in piping system having a function to manage, control, and direct fluid flow by opening and closing some fluid to get lower pressure. The operation of valve can be conducted manually by changing an angle position of handle, wheel, or pedal. In oil and gas industry, automatic operation is mostly used by using hydraulic, pneumatic, and electric energy. There are some types of valves every gas and oil engineer should know about.

Butterfly Valve

Butterfly valve seems to be the most popular one. Butterfly valve is used for low pressure with simple design used for controlling and managing the flow. It is often fully opened and closed in which it requires ¼ round circle. In the bottom of handle and lever, it contains scale used for reading the position of opening and closing’s valve. Butterfly valve is also opening and closing with rotation on the disc so that it can run it quickly.

Needle Valve

Basically, needle valve is a type of valve used in instrument, gage, and meter line service in oil and gas industry. The valve is used for need of throttling process. Why could it be? It is caused that it is very accurate so that you can use it at high pressure and temperature. This valve is actually still categorized into the globe valve. You can know the other types of globe valve at the site below.

Plug Valve

The next type of valve in gas and oil industry that should be known is plug valve. Generally, the use of plug valve is to fully open and close. The main parts of plug valve are similar to gate valve or globe valve. Those are body, packing bolt, stem, plug, and seal. Seal has a function to packing. Packing bolt is similar to gland. Plug is used to control the flow of plug valve. Plug has a hole for passing the oil and gas flow. When the handle is turned to open position, the plug will rotate automatically to the seat and the hole. But, as the handle is turned on on the close position, the plug will rotate to seat and no hole spaces to hold on the flow. It makes the flow stop.

Globe Valve

One of the last common valve types for oil and gas engineers is globe valve. It is a kind of valve designed to manage the scale of regulate or throttling process. Basically, the main parts of globe valve are same as gate valve consisting of body, disc, steam, bonnet, gland, packing, and seat. The flow of fluid in globe valve will have obstacle so that it makes pressure drop bigger than gate valve. The first flow will get seat and turn on. It passes and gets all parts of disc.
