A gas regulator is an internal valve system used externally to control the pressure of a gas cylinder. It helps to reduce the cylinder native pressure down
A gas regulator has a control valve and a safety valve. The control valve regulates the flow of gas, and the safety valve is used to shut off the flow of gas in case of an emergency. The control valve is opened and closed by a knob or lever, which is turned to adjust the amount of gas flowing through the regulator.
There are two basic types of gas pressure regulators: single-stage and two-stage. Single-stage pressure regulators reduce the cylinder pressure to the delivery or outlet pressure in one step. Two-stage pressure regulators reduce the cylinder pressure to a working level in two steps
