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 valve that permits fluid to flow in one direction only.
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 modify (regulate) the fluid flow rate in a process control system. It usually includes an actuator, which responds to a signal from the controlling system and changes the position of the flow controlling element in the valve.
A device that damps, typically a valve or plate (as in the flue of a furnace) for regulating the draft, or a device to stop vibration, typically a shock absorber or snubber.
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 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 is assigned to act in case of emergency.
Flexible joint between two pipes to receive expansion from the pipes.
A physical object that is a projecting flat rim, plate, collar or rib.
A flexible vertical or near vertical pipe for the flow of liquid or gas between the seabed and the surface.
A hollow cone with a tube extending from the smaller end and that is designed to catch and direct a downward flow.
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 functional unit used to blind off a process 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 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 physical object that has a protruding part through which a stream of fluid is directed.
A detector that is intended to detect a pig inside the pipeline or pig receiver.
Is a piping assembly of piping components to be pre-fabricated as one item.
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.
