Johnson Controls 3/8" Pressure Regulator w/ Bracket, Gauge & Valve

The A-4000-138 Remote-Mounted 3/8 in. Pressure-Reducing Station comes completely assembled with a wall mounting bracket, 0 to 30 psig gauge, safety relief valve, and 3/8 in. O.D. compression elbow fittings on the high- and low-pressure sides. The desired output pressure can be easily adjusted between 0 and 30 psig using the black knob. The factory-set safety relief valve relieves overpressures exceeding 25 psig (175 kPa). Pressure adjustments up to 50 psig (350 kPa) can be made; however, the 0 to 30 psig gauge must be replaced with one having a higher scale, and the safety relief valve must be readjusted to the required higher value. Designed to handle input pressures up to 300 psig (2,100 kPa) at air flows exceeding 20 scfm (9.4 l/s), this pressure-reducing station regulates an output pressure within a 0.2 psi (1.4 kPa) variation with a 20 psi (140 kPa) variation in input pressure.
