  2. Pressuretrol - Wikipedia

    en.wikipedia.org/wiki/Pressuretrol

    The main setting is accessible from the outside of the controller, but the differential is often located inside the controller box, and typically the cover must be removed by removing a screw to access the differential control. If the main setting is a cut-in setting, then the differential setting sets the cut-out setpoint by adding to the cut ...

  4. Reduced pressure zone device - Wikipedia

    en.wikipedia.org/wiki/Reduced_pressure_zone_device

    The reduced pressure is guaranteed by a differential pressure relief valve, which automatically relieves excess pressure in the chamber by discharging to a drain. Four test cocks are installed to allow an inspector to verify proper operation of the valve with a differential pressure meter.

  5. Control valve - Wikipedia

    en.wikipedia.org/wiki/Control_valve

    A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.

  6. Pressure regulator - Wikipedia

    en.wikipedia.org/wiki/Pressure_regulator

    Pressure regulator for domestic water supply. Outlet pressure is set with the blue handwheel and shown on the vertical scale. A water pressure regulating valve limits inflow by dynamically changing the valve opening so that when less pressure is on the outside, the valve opens up fully, and too much pressure on the outside causes the valve to shut.

  7. Poppet valve - Wikipedia

    en.wikipedia.org/wiki/Poppet_valve

    The valve stem D moves up to open the valve discs C. James Watt was using poppet valves to control the flow of steam into the cylinders of his beam engines in the 1770s. A sectional illustration of Watt's beam engine of 1774 using the device is found in Thurston 1878:98, [ 13 ] and Lardner (1840) provides an illustrated description of Watt's ...

  8. Valve guide - Wikipedia

    en.wikipedia.org/wiki/Valve_guide

    The upper part of the valve stem, within the rocker box, is lubricated by oil. If this oil travels unchecked along the valve stem, engine HC emissions will become excessive. To control this, an elastomeric seal is fitted over the top of the valve guide. These may wear or stiffen with age, so are usually replaced whenever valves are removed for ...

  9. 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 ...
