Various components form an integral part of the oil and gas industry’s efficient functioning. One such crucial component that helps in the seamless operation of the equipment used is a Valve.
There are tons of fluid being transported through a secured and safe pipeline system. But, the flow is controlled by a mechanism. This control of flow accurately is done with the help of valves.
A valve is a tool or equipment that regulates, controls, or directs the flow of a fluid by opening, closing, or partially blocking fluid flow. Valves help to regulate the flow and pressure of fluid within a system.
This is an essential topic in the oil and gas courses for mechanical engineers.
Valve categories used in Oil and gas industry
Valves are generally selected depending on the requirements. Also, different types of valves chosen for the same function will cost differently. Therefore, selecting the suitable valve is not just operation dependent, but you also have to consider the economic aspect. You will get better insights on the same in the oil and gas training courses online.
The different categories of valves used in the piping industry are:
- Gate Valve
- Globe Valve
- Check Valve
- Plug valve
- Ball Valve
- Butterfly Valve
- Needle Valve
- Pinch Valve
- Pressure Relief Valve
A gate valve is the commonly used type of valve in any piping industry. These valves only support the linear motion, such as starting or stopping fluid flow. During operation, these valves are either in a fully open or fully closed position. Gate valves are used in the flow system that transports air, fuel gas, feedwater, steam, etc.
Globe valve is generally used to stop, start, and regulate fluid flow. Globe Valves are used in systems where flow control, as well as leak management, is crucial. Globe valves are costlier than gate valves.
The check valve prevents backflow in the piping system through an automatic mechanism. The check valve has a self-activated mechanism where the pressure of the fluid passing through a pipeline opens the valve, while any reversal of flow will close the valve.
Plug valves control flow using tapered or cylindrical plugs. The valve allows only a quarter-turn rotary motion. Plug valves are the best when tight shutoff is essential, and these are reliable in high-pressure or high-temperature environments.
Ball valves have quick-acting 90-degree turn handles for easy on-off control to regulate the flow. These are one of the choicest options as they are faster and easier to operate than gate valves.
A Butterfly valve is a quarter-turn rotary motion valve used to stop, regulate, and start the flow. Butterfly Valve is the best option for large valve applications as it is lightweight in design and requires considerably less space than other valves.
Needle valves and globe valves are similar in design. The slight variation is the sharp needle-like disk that is absent in a globe valve. These valves are used in small diameter piping systems when fine and accurate flow control is required.
The pinch valve is otherwise known as clamp valve. Pinch Valve is ideally suited for the handling of slurries, liquids with large amounts of suspended solids. It uses a pinch mechanism to start, stop and control the flow.
Pressure Relief Valve
These valves are spring-automated and used to protect the piping system. This valve helps to return to the desired pressure during overpressure events.
This was a brief description of the types of valves used in the piping system. To get in-depth details about each type of valve, you can check our online course for Piping engineering.
