Electronic Pressure Regulators

QB3 electronic pressure regulators handle reverse flows of 25 scfm at 100 psi.

Backpressure as well as high-relief applications are possible without a quick exhaust valve and additional plumbing. A solid-state sensor monitors pressure at the work port, then the regulator adjusts pressure by filling or exhausting air from the system. It can regulate pressure, vacuum, or be used as a programmable pressure-relief valve.
