2. Pressure regulator - Wikipedia

   en.wikipedia.org/wiki/Pressure_regulator

   Diagram symbols for pressure reduction and back pressure regulators. The conceptual difference is mainly in which side the feedback is taken from. A pressure regulator is a valve that controls the pressure of a fluid to a desired value, using negative feedback from the controlled pressure. Regulators are used for gases and liquids, and can be ...

3. List of valves - Wikipedia

   en.wikipedia.org/wiki/List_of_valves

   Pressure regulator or pressure reducing valve (PRV): reduces pressure to a preset level downstream of the valve; Pressure sustaining valve, or back-pressure regulator: maintains pressure at a preset level upstream of the valve; Presta valve, Schrader valve, or Dunlop valve, holds the air inside bicycle tires; Pulse valve, extremely fast pulsing ...

4. Diaphragm valve - Wikipedia

   en.wikipedia.org/wiki/Diaphragm_valve

   Diaphragm valves can be controlled by various types of actuators e.g. manual, pneumatic, hydraulic, electric etc. The most common diaphragm valves use pneumatic actuators; in this type of valve, air pressure is applied through a pilot valve into the actuator which in turn raises the diaphragm and opens the valve. This type of valve is one of ...

5. Diaphragm (mechanical device) - Wikipedia

   en.wikipedia.org/wiki/Diaphragm_(mechanical_device)

   The action of the diaphragm is very similar to the action of a plunger with the exception that a diaphragm responds to changes in pressure rather than the mechanical force of the shaft. A diaphragm pressure tank is a tank which has pressurant sealed inside on one side of the diaphragm. It is favored in certain applications due to its high ...

6. 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 ...

7. Engineering drawing abbreviations and symbols - Wikipedia

   en.wikipedia.org/wiki/Engineering_drawing...

   The older symbol for this was a small script (italic) f (see herein f). Later the ASA convened upon a letter V (specifically a sans-serif V) touching the surface. Soon this evolved into the "check mark" sign with accompanying number that tells the reader a max roughness value (RMS, microinches or micrometres) for the machined finish, to be ...

8. Rupture disc - Wikipedia

   en.wikipedia.org/wiki/Rupture_disc

   A rupture disc is a type of sacrificial part because it has a one-time-use membrane that fails at a predetermined differential pressure, either positive or vacuum and at a coincident temperature. The membrane is usually made out of metal, [1] but nearly any material (or different materials in layers) can be used to suit a particular application ...

9. Flow control valve - Wikipedia

   en.wikipedia.org/wiki/Flow_control_valve

   These valves achieve this using pressure-compensated mechanisms, which automatically adjust the valve opening to ensure a steady flow rate. Some designs incorporate a dual-chamber configuration that enhances regulation at lower pressures, improving stability in applications such as irrigation, industrial water systems, and municipal water ...
