Why Industrial Valves Are Important in Oil & Gas
Valves are among the most important mechanical components within an oil and gas facility. Their primary purpose is to control the movement of oil, gas, water, chemicals, and other process fluids. However, their role goes far beyond simple flow control.
A properly selected valve can help operators isolate equipment during maintenance, prevent unwanted backflow, regulate process conditions, minimise leakage, and protect critical assets from excessive pressure. Valve reliability is particularly important in oil and gas applications because valve failure can lead to production interruptions, environmental incidents, equipment damage, or serious safety risks.
The selection process should consider factors such as operating pressure, temperature, fluid characteristics, pipe size, flow requirements, corrosion potential, emission requirements, maintenance needs, and applicable industry standards.
1. Ball Valves
Ball valves are widely used throughout oil and gas facilities because they provide reliable shutoff and quick operation. Their design uses a rotating ball with a central opening to control flow. When the valve is fully open, the bore provides a relatively unrestricted flow path, while rotating the ball 90 degrees closes the valve.
Ball valves are commonly used in pipelines, wellhead systems, gas processing facilities, storage systems, terminals, and refinery applications.
Trunnion-mounted ball valves are particularly suitable for demanding high-pressure applications. They can incorporate features such as double block and bleed capability, cavity relief, emergency sealant injection, fire-safe construction, and fugitive emission control. Flowlink’s trunnion-mounted ball valve range includes designs compliant with standards such as API 6D, API 608, ISO 17292, and ASME B16.34.
Their major advantages include:
- Fast quarter-turn operation
- Reliable shutoff
- Low pressure drop
- High pressure capability
- Suitable designs for gas and liquid services
- Availability in specialised materials and configurations
For critical isolation applications, selecting the appropriate ball valve design is essential for achieving dependable long-term performance.
2. Gate Valves
Gate valves are commonly used when full flow or complete isolation is required. Instead of regulating flow through a partially open position, a gate valve is generally designed to operate in either a fully open or fully closed position.
This makes gate valves suitable for applications where maintaining a low pressure drop through the pipeline is important. They are frequently used in transmission pipelines, oil and gas processing facilities, storage systems, and other applications where reliable isolation is required.
Gate valves are available in different configurations and materials to accommodate various pressure, temperature, and fluid conditions. When used correctly, they can provide robust isolation and long service life.
However, gate valves are generally not the first choice for continuous throttling because partially opening the valve can result in undesirable flow characteristics and increased wear.
3. Globe Valves
Globe valves are designed primarily for flow regulation and throttling. Their internal configuration allows operators to adjust the flow rate with greater precision than many isolation valve designs.
In oil and gas facilities, globe valves may be used in process control systems, pressure regulation applications, bypass systems, and other services where accurate flow adjustment is required.
Because throttling can generate pressure losses, globe valves need to be selected according to the specific process conditions. Correct sizing is particularly important because an incorrectly sized valve can negatively affect control accuracy, energy efficiency, and equipment performance.
For automated applications, globe valves can also be integrated with suitable actuation and control systems.
4. Check Valves
Check valves are designed to allow fluid to flow in one direction while preventing reverse flow. They are particularly important in oil and gas systems because unwanted backflow can damage pumps, compressors, pipelines, and other equipment.
Depending on the application, different check valve designs can be used, including swing, piston, lift, and other specialised configurations.
Check valves can be installed in pipeline systems, pump discharge lines, compressor systems, process units, and other locations where reverse flow must be controlled.
Selecting the correct check valve requires consideration of flow velocity, pressure, temperature, fluid properties, installation position, and potential pressure surge.
5. Butterfly Valves
Butterfly valves use a rotating disc to control flow and are often selected when compact construction, lower weight, and efficient operation are important.
They can be used in a variety of oil and gas applications, particularly in larger diameter piping systems. Depending on the design, butterfly valves can provide effective isolation and flow control while requiring less space than some larger valve types.
The selection of seat material, body material, pressure class, actuator, and disc design is important when using butterfly valves in demanding environments.
For automated systems, pneumatic or electric actuation can be added to enable remote operation and integration with plant control systems.
6. DBB Valves
DBB valves, or Double Block and Bleed valves, are particularly important in applications where positive isolation is required. A DBB arrangement provides two independent sealing barriers with a bleed or vent point between them.
This configuration can help operators verify isolation and safely release trapped pressure from the cavity between the barriers. DBB valves can therefore be valuable in applications involving maintenance, equipment isolation, hazardous fluids, and critical process systems.
They are commonly considered for pipeline systems, terminals, storage facilities, refinery applications, metering systems, and other areas where enhanced isolation is required.
Flowlink provides DBB valves and SBB DBB solutions as part of its oil and gas valve portfolio.
7. API Valves
The term API valves generally refers to valves designed, manufactured, tested, or certified according to applicable American Petroleum Institute standards.
API standards are widely referenced throughout the oil and gas sector because they establish technical requirements for equipment used in demanding petroleum and natural gas applications.
For example, API 6D is associated with pipeline and pipeline valve requirements, while other API standards apply to different valve types and services.
Using appropriately specified API valves can help project teams meet technical requirements and provide greater confidence regarding valve design, testing, materials, and performance.
It is important to note that compliance requirements depend on the specific valve, service, project specification, and applicable standard. Engineers should always verify the required standards before purchasing or installing valves.
8. Pipeline Valves
Pipeline valves are essential for transporting crude oil, refined products, natural gas, and other fluids over long distances. These valves allow operators to isolate pipeline sections, control flow, manage maintenance activities, and support emergency shutdown procedures.
Ball valves and gate valves are frequently considered for pipeline isolation because they can provide reliable shutoff and are available in designs suitable for high-pressure services.
Pipeline valve selection should take into account pipeline diameter, operating pressure, temperature, fluid characteristics, corrosion conditions, installation environment, actuator requirements, and applicable standards.
Flowlink’s oil and gas solutions include valve and actuation systems for pipeline management and emergency shutdown applications.
9. Upstream Valves
Upstream valves are used in exploration, drilling, production, wellhead, and gathering applications. These environments can involve high pressure, variable temperatures, corrosive fluids, hydrocarbons, sand, and other challenging conditions.
Valve reliability is particularly important in upstream operations because equipment may be located in remote or difficult-to-access areas. Maintenance and replacement can therefore be expensive and time-consuming.
Common upstream valve applications include wellheads, flowlines, gathering systems, separators, production facilities, and associated process equipment.
Valve materials and sealing systems should be carefully selected according to the characteristics of the produced fluids and the expected operating conditions.
10. Downstream and Refinery Valves
Downstream valves are used in refineries, petrochemical plants, gas processing facilities, storage terminals, and other processing environments.
Refinery applications can involve high temperatures, corrosive chemicals, hydrocarbons, steam, and complex process conditions. As a result, refinery valves need to be selected with careful consideration of temperature resistance, pressure rating, materials, sealing technology, emissions, and process compatibility.
Typical refinery applications include distillation units, cracking units, reforming units, hydrotreating units, blending systems, storage tanks, compressor skids, and pipelines.
Flowlink’s refining and LNG solutions are designed for demanding applications including distillation columns, cracking units, reforming units, hydrotreating units, blending tanks, LNG terminals, compressor skids, and pipelines.
How to Choose the Right Industrial Valve for Oil & Gas
Choosing the correct valve requires more than simply selecting a valve based on pipe size. Engineers and procurement teams should assess the complete operating environment before finalising a valve specification.
Operating Pressure
The valve must be capable of safely handling the maximum expected operating and design pressure. High-pressure systems may require specialised valve designs such as trunnion-mounted ball valves or other high-pressure configurations.
Operating Temperature
Temperature affects body materials, seals, seats, lubrication, and overall valve performance. High temperature and cryogenic services require specially designed valves.
Fluid Characteristics
The type of fluid being handled is another major consideration. Crude oil, natural gas, refined products, chemicals, sour gas, and other fluids may require different materials and sealing arrangements.
Flow Requirements
The valve must be correctly sized according to the required flow rate and system conditions. Oversized or undersized valves can negatively affect process performance and control.
Isolation Requirements
If positive isolation is critical, engineers may consider ball valves, gate valves, or DBB configurations depending on the application.
Automation Requirements
Many modern oil and gas facilities require remote or automated valve operation. Pneumatic, electric, hydraulic, or other actuation systems can be selected according to the application and control philosophy.
Flowlink also provides control valve and actuation solutions for plant and flow control applications.
