Pressure Values
Likely intended to be "Pressure Valves," which are mechanical devices that regulate or control the flow of a fluid by opening, closing, or partially obstructing passageways based on pressure.
Zener Diode
Specialty diode designed to reverse-bias conduct only after a specific voltage value is attained. Used in electronic voltage regulators.
Voltage Regulator
An electrical device designed to automatically maintain a constant voltage level, ensuring electrical stability.
Semiconductor
Material that can act as conductors or insulators depending on how its structure is arranged; elements that have four electrons in the valence shell.
