A physical object for storing energy, and which after discharge may be recharged.

A cooler that is intended to use air as the cooling medium.

A dynamic compressor in which the gas is accelerated by the action of a bladed rotor and where the main flow is along the rotation axis of the rotor.

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 rotary valve that has a ball closure member.

A valve that has one seat which provides a seal, and a bleeder line and valve that are tapped into the block valve's bonnet.

A physical object intended to compress and supply air or gas at medium pressure and medium volume flow.

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 rotary valve that has a closure member of a disc type with a shaft parallel, or near parallel, to the plane of the disc, with an axis of rotation transverse to the flow direction.

A dynamic compressor in which one ore more impellers accelerate the gas and where the main flow through the impeller is radial.

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 valve that can be used to obstruct the fluid passing inside, and has the ability to reduce the pressure from the inlet port to the outlet port.

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

A control valve that is intended to operate at high temperature, and admit water into a deluge system.

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 membrane valve that is a membrane valve where the closure member is a resilient diaphragm being forced against a port.

A block and bleed valve that is incorporating two seats, each of which provides a seal, and a means of venting the space between the seats. The seats may isolate with the pressure differential acting in the same or in opposite directions depending on the design.

A valve that is intended for subsurface control/check operation.

A control valve that uses a rotating disc as closing element, and with a design that causes the disc to take a slightly eccentric path during actuation.

A valve that has a closing member which is an eccentric rotating disc.

A physical object that is intended to deliver or exhaust volumes of vapour or gas at low differential pressure.

A tank or vessel in which a process stream is charged or pumped and where lighter products flash off or vaporize and are drawn off at the top. The remainder heavier fractions are drawn off at the bottom of the vessel.

A regulator that normally use the differential pressure principle across an orifice to control the valve trim and regulate flow.

A static device generating centrifugal force from an incoming flow which separates solid or liquids from a gas of a different density.
