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.
