The QB3 electronic pressure regulator offers reverse flow rates of more than 25 scfm at 100 psi. Makes backpressure and high relief applications possible without needing a quick exhaust valve or additional plumbing. Uses a solid-state pressure sensor to monitor pressure at the work port, and then adjusts the regulator to the desired pressure by filling or exhausting air from the system. Can be calibrated to operate through atmosphere and regulate vacuum or be used as a programmable pressure relief valve.
