Common Valves Used in the Oil & Gas Industry.

Control valves are valves that provide process control over flow rate, pressure, and temperature in the oil and gas industry. They work by varying the size of the flow passage way as directed by either a hydraulic, pneumatic, or electrical signal sent from a controller. The automatic operation of these valves gives them the ability to be operated remotely, rather than having an operator constantly monitoring and adjusting.

Butterfly valves are used to isolate and modulate a variety of media with low pressure loss. The valve usually comes equipped with an actuator. Their small thickness allows them to fit almost anywhere, while their ease of availability in larger diameters means they can be used in large pipes. When actuated, they are quick to open and close and they provide high reliability with little maintenance.

Ball valves are designed to control the flow of high pressure liquids and gases with minimal pressure drop. They are quick to open and close, and have a tight seal with low torque. Their ease of operation, repair, and versatility lends the ability to be used in a variety of locations.

Check valves are used to prevent reverse flow through the pipes. Their service helps to protect pumps and equipment that could be damaged by backflow, reducing maintenance and downtime of the system. These valves have a low pressure drop, which increases energy savings. They also help to reduce chatter within the pipes.

Globe valves are often used for isolation and throttling services. Installation is simple due to their easily machined valve seats. They offer a tight shut off ability, and the simple linear motion allows for a quick open and close of the valve.
