Available oxygen cleaned for oxygen service
The QB3H is an electronic pressure regulator capable of operating at high pressures (to 500psig/34.47 bar) and
high forward and relief flows (to 50scfm/1416slpm). The QB3H consists of two solenoid valves which add or
subtract pressure to the pilot of an integral volume boosting regulator. An internal stainless steel pressure sensor
measures the high pressure output of the integral volume booster and sends this signal to the onboard controller. This controller
then modulates the two solenoid valves to match the integral volume booster’s output pressure to the user’s requested
command signal. All brass body units are oxygen cleaned at the factory.
