Oil and gas storage systems—whether for crude oil tanks, liquefied natural gas (LNG) terminals, or refined fuel reservoirs—rely on specialized valves to ensure safety, prevent leaks, and maintain efficient fluid control. The high pressures, flammable nature, and extreme temperatures of stored oil and gas demand valves that can withstand harsh conditions while minimizing risk. This article breaks down the key valve types used in oil and gas storage, their roles, and why they’re indispensable, helping you answer how to select the right valves for oil and gas storage systems to ensure reliability and compliance.
Ball valves are widely used in oil and gas storage for their quick quarter-turn operation, high-pressure tolerance, and ability to handle both liquids and gases. Their design includes a hollow metal ball with a bore (hole) that aligns with the pipeline when open and blocks it when rotated 90 degrees.
Emergency shutoff: Installed near storage tank outlets or pump stations, ball valves can be closed in seconds to stop flow during leaks, fires, or equipment failures—far faster than gate valves (which require multiple turns).
Loading/unloading control: Used to regulate the flow of oil or gas between storage tanks and transport vehicles or pipelines. Their precise on/off action prevents overfilling or spills.
High-pressure storage service: Suitable for high-pressure storage systems, such as compressed natural gas (CNG) reservoirs or crude oil storage at offshore platforms, where they can handle pressures up to 10,000 psi.
Ball valves are preferred for storage because they’re low-maintenance (fewer moving parts than gate valves) and resistant to cavitation when handling high-velocity flows. For LNG storage, cryogenic ball valves maintain sealing integrity even in extreme cold, while metal-seated ball valves withstand the abrasive nature of crude oil,which may contain sand or sediment.

Check valves (also called non-return valves) are critical safety components in oil and gas storage, designed to allow fluid flow in only one direction—preventing reverse flow that could damage tanks, pumps, or other equipment. Reverse flow in storage systems often occurs due to pressure fluctuations or backpressure from adjacent pipelines.
Tank overfill prevention: Installed on tank inlet pipes, check valves stop oil or gas from flowing back into the pipeline if the tank is full, avoiding spills or tank damage.
Pump protection: Placed on the discharge side of storage pumps, check valves prevent fluid from flowing backward into the pump when it’s turned off—this avoids “water hammer” (sudden pressure spikes that crack pump components) and extends pump life.
LNG boil-off gas (BOG) management: In LNG storage, check valves control the flow of BOG (natural gas vaporized from LNG) to compression systems, preventing BOG from flowing back into the tank and increasing pressure beyond safe limits.
Check valves require no manual operation—they open and close automatically based on flow direction—making them reliable for 24/7 storage operations. Common types used in oil and gas storage include swing check valves (for low-to-medium pressure) and ball check valves (for high-pressure or high-velocity flows), both of which are built to resist corrosion from oil and gas and harsh weather.

Globe valves are used in oil and gas storage for applications that require precise flow throttling (adjusting flow rate) rather than just on/off control. Their design features a movable plug (or disc) that fits into a seat, with a handwheel or actuator that raises or lowers the plug to regulate flow.
Tank level control: Installed on storage tank fill lines, globe valves adjust the flow rate of oil or gas into the tank, preventing rapid filling . This is critical for maintaining safe tank levels (typically 85–90% capacity to allow for thermal expansion).
Pressure regulation: Used in LNG or CNG storage to reduce high pipeline pressure to the lower pressure required for tank filling. Globe valves provide smooth, gradual pressure reduction, avoiding sudden pressure spikes that stress tank walls.
Boil-off gas (BOG) pressure control: In LNG storage, globe valves throttle the flow of BOG to maintain stable tank pressure—too much pressure can damage the tank, while too little can allow air to enter (creating a flammable mixture).
Globe valves offer superior throttling accuracy compared to gate or ball valves, making them essential for applications where flow rate must be carefully managed. They’re also designed for tight sealing, which prevents leaks when fully closed—critical for storing flammable or toxic oil and gas. For high-temperature storage (e.g., heated crude oil), metal-seated globe valves withstand temperatures up to 600°C, while cryogenic globe valves handle LNG’s extreme cold.

Butterfly valves are a cost-effective, compact option for oil and gas storage systems with large-diameter pipelines (12+ inches). Their design includes a rotating disc (shaped like a butterfly wing) that opens or closes with a quarter-turn, making them faster to operate than gate valves while being lighter and more affordable.
Tank farm manifold control: Used to direct flow between multiple storage tanks in a tank farm, butterfly valves allow operators to switch which tank is being filled or emptied without shutting down the entire system.
Firewater system isolation: Installed in storage facility firewater pipelines, butterfly valves quickly open to supply water to fire suppression systems in case of a fire—their fast operation is critical for containing blazes involving flammable oil and gas.
Wastewater and drainage control: Used in storage facilities to manage wastewater from tank cleaning or rainwater runoff, preventing contamination of stored oil and gas or the environment.
Butterfly valves are ideal for storage because they’re space-efficient (their compact design fits in tight areas) and require minimal maintenance. For oil and gas applications, resilient-seated butterfly valves (with rubber or PTFE seals) provide tight sealing for non-corrosive fuels, while metal-seated butterfly valves handle crude oil or corrosive gases. They’re also compatible with automated actuators, making them easy to integrate into remote-monitored storage systems.
