Ross Controls 5213B4015 Regulator

Ross Controls 5213B4015 Regulator is a mid-size, modular pressure regulator in the Ross FRL lineup, designed for 1/2-inch NPT port connections and a regulated output up to 150 psig (10.3 bar). This model sits in the mid-size series which delivers flow up to 100 scfm with 1/2" ports, making it suitable for maintaining stable downstream pressure in pneumatic systems and automation equipment. The 5213B4015 corresponds to the 1/2" port size and a 0–150 psig regulation range; neighboring options in the same family include 5212B4015 (0–50 psig) and 5211B4015 (0–100 psig). By default, these regulators use NPT port threads; for BSPP (G) threads, add a C prefix to the model number (e.g., C5213B4015). These regulators are intended to sustain a chosen pneumatic pressure in compressed-air systems, supporting consistent performance in industrial machinery, tooling, and other applications where reliable downstream pressure is required.
