What Types of Valves Used in Oil and Gas Industry?

The oil and gas industry uses various types of valves to control the flow of fluids within pipelines, processing units, and other equipment. These valves are essential for ensuring safe and efficient operations in upstream (exploration and production), midstream (transportation and storage), and downstream (refining and distribution) sectors of the industry. I this article, we will share basic information regarding “What types of valves are used in the oil and gas industry”.

Ball Valves

Ball valves are versatile and commonly used in the industry. They consist of a spherical closure element (the ball) with a hole through it. When the hole aligns with the pipeline, fluid can flow through, and when the ball is rotated 90 degrees, the hole is perpendicular to the pipeline, stopping the flow. Ball valves offer quick operation, tight shut-off, and are suitable for high-pressure applications.

Gate Valves

Gate valves are linear motion valves that use a wedge-shaped gate to control flow. They offer minimal resistance to fluid flow when fully open, making them suitable for applications that require minimal pressure drop. However, they are not ideal for controlling flow rates. These valves are often used in isolation applications, where the flow needs to be completely shut off or allowed to pass unimpeded.

Globe Valves

Globe valves are versatile and can be used to regulate, start, or stop fluid flow. They have a spherical disc and a movable stem that adjusts the position of the disc to control flow. Globe valves offer good throttling capabilities, making them suitable for applications requiring precise flow control.

Check Valves

Check valves, also known as non-return valves, allow fluid flow in only one direction. They automatically prevent backflow, which can be crucial in preventing damage to equipment and maintaining process efficiency. Check valves are used in pipelines, pumps, compressors, and other systems where preventing reverse flow is essential.

Butterfly Valves

Butterfly valves have a disc that rotates around a central axis to control flow. They are lighter and more compact compared to ball valves and are often used for larger pipe sizes. Butterfly valves are used in applications where space and weight considerations are important, and they are commonly found in pipeline systems.

Plug Valves

Plug valves use a cylindrical or tapered plug to control flow by rotating the plug within the valve body. They are versatile and can be used for on-off or throttling applications. Plug valves are used in various oil and gas processes, including refining and petrochemical applications.

Safety Relief Valves

Safety relief valves are designed to automatically release excess pressure from a system to prevent equipment damage or catastrophic failure. They are a crucial component for maintaining safe operating conditions in pressure vessels, pipelines, and other systems.

Control Valves

Control valves are specialized valves used to regulate fluid flow based on signals from a control system. They consist of a valve body, an actuator, and a control mechanism. The control mechanism adjusts the position of the valve disc or plug to achieve the desired flow rate. Control valves are crucial for maintaining process parameters within specific limits.

Needle Valves

Needle valves have a slender, needle-like plunger that allows for precise flow control in small increments. They are commonly used in applications where fine adjustments to flow rates are required, such as sampling and calibration processes.

Diaphragm Valves

Diaphragm valves use a flexible diaphragm to control the flow of fluid. They are often used in applications requiring high purity and minimal contact between the fluid and the valve body.

Choke Valves

Choke valves are specifically designed to control the flow rate of fluids, particularly in wellheads and production facilities. They are used to manage pressure and flow during oil and gas production to prevent equipment damage and ensure safe operations

Pressure Reducing Valves

Pressure reducing valves, also known as pressure regulators, lower the pressure of a fluid stream to a desired level. They are used in gas distribution systems and various applications where precise pressure control is necessary.


In conclusion, the selection of valve types in the oil and gas industry depends on the specific application, the nature of the fluid being transported, pressure and temperature conditions, and the required level of flow control. Each type of valve has its own advantages and disadvantages, and engineers must carefully consider these factors to ensure the safe and efficient operation of the facilities and systems.
