Ball valve

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it.

Control valve

A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller.

A flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car or tram wheel.

Fluid dynamics

In physics and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids - liquids and gases.

Gate valve

A gate valve, also known as a sluice valve, is a valve which opens by lifting a round or rectangular gate/wedge out of the path of the fluid.

Globe valve

A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material (an element, compound, or alloy) that is typically hard when in solid state, opaque, shiny, and has good electrical and thermal conductivity.

Natural rubber

Natural rubber, also called India rubber or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water.

Needle valve

A needle valve is a type of valve having a small port and a threaded, needle-shaped plunger.

An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

Pigging in the context of pipelines refers to the practice of using devices known as "pigs" to perform various maintenance operations.

Plastic pipework

Plastic pipe is a tubular section, or hollow cylinder, made of plastic.

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

A throttle is the mechanism by which fluid flow is managed by the constriction or obstruction.

New!!: Butterfly valve and Throttle · See more »


A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.
