valves

A valve is a mechanical device that regulates the flow of fluids (either gases, fluidised solids, slurries or liquids) by opening, closing, or partially obstructing various passageways.Valves are used in a variety of industrial, military, commercial, and residential applications.

Types of valves -

Ball cock, often used as a water level controller (cistern);

Ball valve, which is good for on/off control;

Bibcock;

Blast valve, used to prevent rapid overpressures in a fallout shelter or bunker;

Butterfly valve, particularly in large pipes;

Cock, colloquial term for a small valve;

Gate valve, mainly for on/off control;

Globe valve, which is good for regulating flow;

Hydraulic valve (diaphragm valve);

Check valve or Non-return valve, allows the fluid to pass in one direction only;

Pilot valves regulate flow or pressure to other valves;

Plug Valve, for on/off control;

Solenoid valve, an electrically controlled hydraulic or pneumatic valve;

Tap (valve)Tap (British English), Faucet (American English) is the common name for a valve used in homes to regulate water flow;

Rotary valves and piston valves are parts of brass instruments used to change their pitch.Different valves may be used for a variety of purposes:

A flow control valve maintains a constant flowrate through the valve.

A heart valve regulates blood flow through the heart in many organisms.

A poppet valve is commonly used in piston engines to regulate the fuel mixture intake and exhaust. The sleeve valve is another valve type used for this purpose.

A pressure reducing valve reduces pressure to a preset level downstream of the valve.

A pressure sustaining valve maintains pressure at a preset level upstream of the valve.

A regulator is used in diving regulatorSCUBA diving equipment and in gas cooking equipment to reduce the high pressure gas supply to a lower working pressure

A safety valve or relief valve operates automatically at a set differential pressure to correct a potentially dangerous situation, typically over-pressure.

A three-way valve routes fluid from one direction to another.

Vacuum breaker valves prevent the back-siphonage of contaminated water into pressurized, potable water supplies.

Other uses of the term -

in electronics, a valve (British English) = vacuum tube (American English)

in electrical engineering, a valve is a component of the static inverters of a high voltage direct current power transmission system
