  2. Four-terminal sensing - Wikipedia

    en.wikipedia.org/wiki/Four-terminal_sensing

    Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...

  4. Automatic balancing valve - Wikipedia

    en.wikipedia.org/wiki/Automatic_balancing_valve

    Traditional control valves make it inevitable. As we size a control valve, the K v calculated almost certainly will not match the K v of the nearest appropriate valve. For example, a K v calculation of 4.5 m 3 /h would most likely lead to the selection of a valve with a K v = 6.3 m 3 /h. This means the valve is capable of delivering 40% more ...

    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.

  6. Thermal expansion valve - Wikipedia

    en.wikipedia.org/wiki/Thermal_expansion_valve

    A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in vapor-compression refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the refrigerant that flows out of the evaporator ...

  8. 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 ...
