An equipment class that contains classes that normally are the responsibility of a department for mechanical engineering.

A mechanical controller that is intended to position a given item in accordance with a received input signal.

A seal that comprises of a set of one or more rotating and stationary seal faces, together with auxiliary hardware, separated by a film of fluid intended to reduce flow loss around a rotating shaft to an acceptable level.

An 'equipment class' that is a class of devices engaged in meteorological observations

An artefact for the calibration of flow meters.

A device that is capable of three-phase metering of liquid, oil and gas.

An equipment class that contains classes that not covered by any other parent class.

A physical object intended to be used for fluid mixing processes typically a rotating piece of equipment comprised of a driver such as a motor which rotates an agitator immersed in the fluid(s) that need to be mixed.

Is a portable, self-contained cell phone tower transported by truck and deployed on a temporary basis to provide expanded cellular network coverage for limited duration events or emergency situations that overwhelm permanent tower infrastructure.

An aerial work platform (AWP), elevating work platform (EWP), or mobile elevating work platform (MEWP) is a mechanical device used to provide temporary access for people or equipment to inaccessible areas, usually at height.

A gas flow damper that is able to stay in any position between fully open and fully closed.

A device that generates rotational kinetic energy.

A switchgear and controlgear that houses motor starters to control electric motors.

An operated valve that is opened and closed with a motor.

Is a bracket intended to attach an item to another item.

An analyser giving as output a signal that represents more than one physical properties of the analysed substance.

A flow meter for the metering a mixture of two or more fluid phases.

A valve not designed to regulate flow (e.g. on/off). A valve with multiple orifices or flow-restriction device to control fluid flow. Includes an actuator that needs auxiliary power to operate.

A valve not designed to regulate flow (e.g. on/off). A multi port valve which has the possibility of multiple distinct paths for flow through it. Includes an actuator that needs auxiliary power to operate.

A valve that has three or more ports arranged to switch flow.

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 globe valve that has a closure member with the shape of a conical plug (needle) which closes into a small seat.

A gas flow damper that prevents back flow in a duct.
