Regulator set

A pressure regulator is a valve that controls the pressure of a fluid or gas to the desired value. Regulators are used for gases and liquids and can be an integral device with a pressure setting, a restrictor, and a sensor all in one body, or consist of a separate pressure sensor, controller, and flow valve.
Pressure regulators
reduce a supply (or inlet) pressure to lower outlet pressure and work to maintain this outlet pressure despite fluctuations in the inlet pressure
.
Regulator set consists of:
Air regulator
Set and display air pressure supplied to the vessel.
Filter regulator
Clean the air and supply it to the dispenser.
