2. 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 ...

3. Check valve - Wikipedia

   en.wikipedia.org/wiki/Check_valve

   Tilting-disc inconel check valve Check valve symbol on piping and instrumentation diagrams. The arrow shows the flow direction. Vertical lift check valve. A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. [1]

4. Valve actuator - Wikipedia

   en.wikipedia.org/wiki/Valve_actuator

   Air (or other gas) pressure is the power source for pneumatic valve actuators. [1] They are used on linear or quarter-turn valves. Air pressure acts on a piston or bellows diaphragm creating linear force on a valve stem. Alternatively, a quarter-turn vane-type actuator produces torque to provide rotary motion to operate a quarter-turn valve.

5. Control valve - Wikipedia

   en.wikipedia.org/wiki/Control_valve

   Pneumatic valve: Actuated using a compressible medium like air, hydrocarbon, or nitrogen, with a spring diaphragm, piston cylinder or piston-spring type actuator; Hydraulic valve: Actuated by a non-compressible medium such as water or oil; Electric valve: Actuated by an electric motor; A wide variety of valve types and control operation exist.

6. Pneumatic circuit - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_circuit

   A pneumatic circuit is an interconnected set of components that convert compressed gas (usually air) into mechanical work. In the normal sense of the term, the circuit must include a compressor or compressor-fed tank.

7. Air compressor - Wikipedia

   en.wikipedia.org/wiki/Air_compressor

   Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.

8. Rotary-screw compressor - Wikipedia

   en.wikipedia.org/wiki/Rotary-screw_compressor

   One pneumatic controls manufacturer puts silicon grease on the seals and gaskets. [14] [15] Mineral oil (but not polyalkylene glycol oil) lubricated compressors are recommended for mineral oil greases coated seals, such as pneumatic high speed 4-way valves and air cylinders that operate without mineral oiler lubricators.

9. Underground pneumatic boring - Wikipedia

   en.wikipedia.org/wiki/Underground_pneumatic_boring

   A piercing tool uses compressed air to bore through the ground. Manufacturers have proprietary standards and control mechanisms. Compressed air is run to the piercing tool through a pneumatic hose. Additionally an oiler attachment is used to send oil along with the compressed air, similar to a jackhammer. Inside the piercing tool is a piston. A ...
