The dual-stage gas regulator is a type of gas regulator designed for multiple cylinder systems. It offers a constant outlet pressure and is ideal for a variety of applications. This type of regulator also features upstream and downstream pressure gauges and a relief valve. These regulators are available with capacities ranging from 160 MJ/h to 500 MJ/h.

The dual-stage gas regulator combines two regulators in one housing, one to control the flow rate and the other to reduce the pressure. The first stage provides a preset gas pressure while the second stage reduces the pressure to a working pressure. These regulators have two safety valves to help minimize the risk of an explosion.

Dual-stage regulators have three major operating elements: a loading mechanism to determine the pressure of the gas to be delivered, a sensing element to measure the pressure against it, and a control element to reduce the pressure in the inlet and outlet.
