    en.wikipedia.org/wiki/Pressure_regulator

    In a no pressure situation, where water could flow backwards, it won't be impeded. A water pressure regulating valve does not function as a check valve. [citation needed] [clarification needed] They are used in applications where the water pressure is too high at the end of the line to avoid damage to appliances or pipes.

    A cracking pressure adjustment knob can be seen at the left side of the valve mechanism. Screwing it in increases the pre-load on the valve spring and increases the pressure difference required to pull the diaphragm in enough to open the valve. Cracking pressure adjusting knob and flow deflector lever on Apeks TX100 demand valve

  4. 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 ...

    A reduced pressure zone device (RPZD, RPZ, or RPZ valve) is a type of backflow prevention device used to protect water supplies from contamination. RPZDs may also be known as reduced pressure principle (RP), reduced pressure principle backflow prevention devices , [ 1 ] [ 2 ] reduced pressure zone assemblies (RPZA), [ 3 ] or reduced pressure ...

  6. Globe valve - Wikipedia

    en.wikipedia.org/wiki/Globe_valve

    Globe valve. A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. [1] Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.

  7. 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 ...
