WATER PRESSURE REGULATOR

A pressure regulator is a control valve that reduces the input pressure of a fluid or gases to a desired value at its output. Regulators are used for gases and liquids, and can be an integral device with an output pressure setting, a restrictor and a sensor all in the one body, or consist of a separate pressure sensor, controller and flow valve.

A regulator is a device for controlling the rate of working of machinery or for controlling fluid or gas flow or pressure. Regulators can be designed to control anything from gases or fluids, to light or electricity. Speed and pressure can be regulated by electronic, mechanical, or electro-mechanical means.

A voltage regulator is a system designed to automatically maintain a constant voltage level. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.
