Electronic Pressure Regulator
The QB3 is an electronic pressure regulator that uses replaceable o-rings as seats and seals. If an application requires special elastomers or materials, all o-rings and seals are replaceable or exchangeable for a new or different elastomer. The o-rings for the intake and exhaust valve are set into a special grove that captures the o-ring but leaves it room to move slightly, and seal correctly for positive shut off. The QB3 incorporates an electronic pressure sensor that senses the downstream pressure at the work port for accurate regulation.
