Gas Pressure Regulators are devices used in gas pipes to maintain the desired pressure level. They are fitted in the gas pipe network at the entry point of the gas supply and are used to maintain gas pressure at the desired level to avoid gas leakage and to supply gas at desired pressure level. Gas pressure regulators have an inlet pipe and an outlet pipe. They also have a pressure adjustment knob. The adjustment knob is used to control the pressure in the system between a preset minimum and maximum value. There are different types of gas pressure regulators available in the market. They all have different features that meet the application requirements they are used in. They are made with a combination of carbon, iron, silicon, copper, nickel, chromium, and a few other elements, depending on the brand and model of the device. A gas pressure regulator's internal structure comprises various chambers, valves, and sensors. These are used to measure the pressure of the gas supply and regulate it according to the desired setting. The exterior is usually made from iron, aluminum, or stainless steel.
