A separator that is based on the difference in specific gravity for the substances to be separated.

A trough that is located along the eaves to catch and carry liquid.

A vessel with a conical shape for filling or dosing purposes.

An arrangement to supply hydraulic power according to specified levels and tolerances.

A turbine in which liquid forces are driving the rotor by the reaction of acceleration of subject liquid flow in the runner while the pressure drops.

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

A drum intended to separate relatively small quantities of liquid from a vapour stream.

A physical object that contains a chamber with several openings.

A valve that is regulated with hand power.

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

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 flowloop that allows a pipeline pig to move from one pipe to another.

A pressure vessel intended for receiving a pig from a pipeline.

A facility on a pipeline for inserting and retrieving a scraper or pig.

A pressure relief valve that uses a pilot valve to indirectly activate the main valve.

A physical object that is a long tube or hollow body intended for conduction of liquid, gaseous or finely divided solid materials, or used for structural purposes.

A fluid conductor that consists of pipe, possibly also including pumps, valves, and control devices, intended for conveying liquids, gases, or finely divided solids.

A lift check valve that has a free gravity or spring loaded piston type closure member.

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

A rotary valve that has a quarter turn action in which the closure member is a cylindrical or tapered plug which operates by rotating on its axis and sealing against a downstream seat.

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