PRDs function based on a simple principle. They consist of a valve that automatically adjusts to maintain a constant downstream pressure, regardless of fluctuations in the upstream supply. When the upstream pressure increases, the valve opens to release excess fluid or gas, and conversely, it closes or narrows when the pressure drops, preventing under-pressure conditions. This mechanism ensures that the system operates within safe parameters, enhancing overall efficiency and reliability.

PRVs come in various designs and configurations to suit different operational needs. Common types include pilot-operated valves, direct-acting valves, and electronic pressure regulators. Pilot-operated valves utilize a small pilot valve to control a larger main valve's position, providing higher sensitivity and flow control. Direct-acting valves are simpler and operate based solely on the downstream pressure, while electronic regulators offer digital control for high-precision applications.
