A gas pressure regulator is a device used to control the pressure in a gas system. Its core function is to stably adjust the gas pressure from a higher input pressure to a required lower output pressure and maintain the stability of the output pressure when the input pressure or gas consumption changes. It is widely used in industries such as industrial production, gas transportation, medical care, laboratories, and aerospace.

Main Types
According to application scenarios and functional characteristics, gas pressure regulators can be classified into the following categories: direct-acting type, indirect-acting type, back pressure regulator, pressure reducing regulator, and precision regulator with a pilot.

Application Scenarios
Industrial Field

• Pressure regulation of fuel gas for gas boilers and heating furnaces to ensure stable combustion.
• Controlling the gas pressure in reactors and pipelines in chemical production to guarantee process safety.
• Pressure stabilization of gas sources for pneumatic control systems (such as cylinders and solenoid valves).

Civil and Commercial Use

• Natural gas inlet pressure regulation, reducing high-pressure gas from municipal pipelines to low pressure suitable for households (e.g., 2000–3000 Pa).
• Gas pressure regulation systems for restaurant kitchens and hotel boiler rooms.

Medical and Laboratory Settings

• Pressure reduction of gas in hospital central oxygen supply systems, lowering the pressure of high-pressure oxygen cylinders to a safe level (e.g., 0.2–0.4 MPa) for patient use.
• Pressure reduction and stabilization for laboratory gas cylinders (such as hydrogen and nitrogen) to ensure experimental safety.

Aerospace

• Pressure control in aircraft fuel systems and hydraulic systems, as well as pressure regulation in rocket propellant delivery.
