The operation of a gas pressure reducer is based on a few fundamental principles. A typical pressure reducer consists of a body, an inlet, an outlet, a diaphragm, and a spring. When high-pressure gas enters the reducer, it pushes against a diaphragm. The pressure exerted on the diaphragm is countered by a spring, which is pre-tensioned to a specific value.

Natural gas regulators can be classified into different types based on their operation and application. The two main types are first-stage and second-stage regulators. First-stage regulators are typically used at the gas distribution level and reduce the high pressure coming from the main gas supply line to an intermediate pressure that is still higher than what consumers require. Second-stage regulators further reduce this pressure to the levels suitable for use in household appliances.
