TYPES OF VALVES	:--
 4-stroke cycle engine valves,  Ball cock, often used as a water level controller (cistern).  Ball valve, which is good for on/off control.  Bibcock, provides a connection to a flexible hosepipe  Blast valve, used to prevent rapid overpressures in a fallout shelter or a bunker.  Butterfly valve, particularly in large pipes.  Check valve or Non-return valve, allows the fluid to pass in one direction only.  Cock, colloquial term for a small valve or a stopcock.  Demand valve on a diving regulator.  Diaphragm valve, a sanitary valve predominantly used in the pharmaceutical industry  Double check valve.  A flow control valve maintains a constant flow rate through the valve.  Freeze valve, in which freezing and melting the fluid creates and removes a plug of frozen material acting as the valve.  Gate valve, mainly for on/off control.  Choke valve, Is a heavy duty valve which controls flow to a certain Flow Coefficient (CV) determined by how far the valve is opened, regularly used in the Oil industry.  Globe valve, which is good for regulating flow.  A heart valve regulates blood flow through the heart in many organisms.  Hydraulic valve (diaphragm valve).  A leaf valve is a one-way valve consisting of a diagonal obstruction with an opening covered by a hinged flap.  Needle valve for gently releasing high pressures.  Pilot valves regulate flow or pressure to other valves.  Piston valves  Plug valve, for on/off control. 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 (PRV), also called pressure regulator, reduces pressure to a preset level downstream of the valve.  A pressure sustaining valve, also called back-pressure regulator, maintains pressure at a preset level upstream of the valve.  Presta and Schrader valves are used to hold the air in bicycle tires.  A Reed valve consists of two or more flexible materials pressed together along much of their length, but with the influx area open to allow one-way flow, much like a heart valve.  A regulator is used in SCUBA diving equipment and in gas cooking equipment to reduce the high pressure gas supply to a lower working pressure  Rotary valves and piston valves are parts of brass instruments used to change their pitch.  A saddle valve, where allowed, is used to tap a pipe for a low-flow need.  A safety valve or relief valve operates automatically at a set differential pressure to correct a potentially dangerous situation, typically over-pressure.  Schrader valves are used to hold the air inside automobile tires.  Solenoid valve, an electrically controlled hydraulic or pneumatic valve.  Stopcocks restrict or isolate the flow through a pipe of a liquid or gas.  Tap (British English), faucet (American English) is the common name for a valve used in homes to regulate water flow.  A three-way valve routes fluid from one direction to another.  Some trap primers either include other types of valves, or are valves themselves  Vacuum breaker valves prevent the back-siphonage of contaminated water into pressurized drinkable water supplies.
