A ball valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A butterfly valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A sealless centrifugal pump where both the impeller and the motor rotor are surrounded by the pumped liquid and where a liner (can) is placed between rotor and stator to isolate the stator from the pumped liquid.

A dynamic pump that contains impellers provided with vanes to generate centrifugal force to achieve the required pressure head.

A choke valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A physical object that is an assembly of pipes and piping parts, with valves and associated control equipment that is connected to the top of a wellhead and is intended for control of fluid from a well.

A gravity separator where two liquid substances separates and where the substance with the less gravity can be skimmed off.

A diaphragm valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A flexible vertical or near vertical pipe for the flow of liquid or gas between the seabed and the surface.

A control valve that is a gate valve and an actuated valve.

A control valve that is a globe valve and an actuated valve.

A cyclone separator intended to separate a fluid by hydraulic forces.

A needle valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A control valve that is also a plug valve and an actuated valve.

A regulator that is controlling/regulating the pressure in a system.

a positive displacement pump which contains a displacing element intended to be moved in a reciprocating movement to exert pressure on a fluid, typically moving within a cylindrical space.

A rigid vertical or near vertical pipe for the flow of liquid or gas between the seabed and the surface.

a positive displacement pump that consists of a chamber containing gears, cams, screws, vanes, plungers or similar elements actuated by relative rotation of the drive shaft or casing and which has no separate inlet and outlet valves.

A distillation column intended to clean gas by washing the gas flow with water or with another liquid entering at the top of the vessel and sprayed in the gas. Typically to remove dust and small particles.

A 'device' intended to separate different types of substances.

A catcher intended to catch and separate liquid slugs from a fluid stream.

A regulator that is intended to keep a temperature within certain boundaries.

A pump that utilizes a liquid annulus held by centrifugal force around the inside of a casing by a single rotor-impeller to compress vapour isothermically.

The wellhead is assembled from, or incorporates facilities for, the upper casing and tubing hangers. This effectively provides the upper termination of the wellbore and provides a mounting position for the surface flow-control equipment or Christmas tree.
