2. Automatic bleeding valve - Wikipedia

   en.wikipedia.org/wiki/Automatic_bleeding_valve

   Brass-bodied float valve. An automatic bleeding valve or air release valve (ARV) is a plumbing valve used to automatically release trapped air from a heating system. Air, or other gas, may collect within plumbing. For water delivery systems to taps and basins, particularly with good main supply pressure, this air is usually flushed through with ...

3. Schrader valve - Wikipedia

   en.wikipedia.org/wiki/Schrader_valve

   The Schrader valve is used on virtually all automobile tires and motorcycle tires and most wider-rimmed bicycle tires.In addition to tube and tubeless tires, Schrader valves of varying diameters are used on many refrigeration and air conditioning systems to allow servicing, including recharging with refrigerant; by plumbers conducting leak-down pressure tests on pipe installations; as a ...

4. Bleed air - Wikipedia

   en.wikipedia.org/wiki/Bleed_air

   Bleed air in aerospace engineering is compressed air taken from the compressor stage of a gas turbine, upstream of its fuel-burning sections.Automatic air supply and cabin pressure controller (ASCPC) valves bleed air from low or high stage engine compressor sections; low stage air is used during high power setting operation, and high stage air is used during descent and other low power setting ...

5. Tire changer - Wikipedia

   en.wikipedia.org/wiki/Tire_changer

   The air pressure system consists of 4 components: air hose, air inflation gauge, inflation pedal and manual pressure bleed valve. The air hose is located near the top of the tire changer, and it allows compressed air to travel into the tire. A specialized end is used on the air hose to clamp firmly onto valve stems of the wheels. The air ...

6. Pneumatics - Wikipedia

   en.wikipedia.org/wiki/Pneumatics

   A pneumatic butterfly valve. Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. [citation needed] The air usually has moisture removed, and a small quantity of oil is added at the compressor to prevent corrosion and lubricate mechanical components.

7. Air-operated valve - Wikipedia

   en.wikipedia.org/wiki/Air-operated_valve

   An air-operated valve, also known as a pneumatic valve, is a type of power-operated pipe valve that uses air pressure to perform a function similar to a solenoid. As air pressure is increased, the compressed air starts to push against the piston or diaphragm walls which causes the valve to actuate. Whether the valve opens or closes depends on ...
