  2. Valve actuator - Wikipedia

    en.wikipedia.org/wiki/Valve_actuator

    The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator. Another valve actuator is visible in the background, with windows to indicate the valve position. A valve actuator is the mechanism for opening and closing a valve. Manually ...

  3. Actuator - Wikipedia

    en.wikipedia.org/wiki/Actuator

    An actuator can be just a mechanism that is directly driven by the motions or forces of other parts of the system. An example is the camshafts that drive the intake and exhaust valves in internal combustion engines, driven by the engine itself.

  4. Hydraulic cylinder - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_cylinder

    A hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. [citation needed] It has many applications, notably in construction equipment (engineering vehicles), manufacturing machinery, elevators, and civil engineering.

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

  6. Pneumatic actuator - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_actuator

    valve with pneumatic diaphragm actuator and "smart" positioner which will also feed back to the controller the actual valve position Pneumatic rack and pinion actuators for valve controls of water pipes. A pneumatic actuator mainly consists of a piston or a diaphragm which develops the motive power. It keeps the air in the upper portion of the ...

  7. Desmodromic valve - Wikipedia

    en.wikipedia.org/wiki/Desmodromic_valve

    The common valve spring system is satisfactory for traditional mass-produced engines that do not rev highly and are of a design that requires low maintenance. [1] At the period of initial desmodromic development, valve springs were a major limitation on engine performance because they would break from metal fatigue.
