QB4 High Flow (200 SCFM) Electronic Pressure Controller
The QB4 high flow electronic control valve is a space-saving, compact closed-loop electronic pressure regulator. The QB4 is made up of two solenoid valves, an internal pressure transducer and an electronic control circuit mounted to an integrated volume booster.
- Full vacuum to 150 PSI (10.34 Bar)
- Flows up to 200 SCFM forward and exhaust
- Wide range of analog and digital command signal options
The output pressure is proportional to an electrical input command signal. The QB4 high flow control valve also provides an electrical monitor signal for output to a panel meter or controller for data acquisition and/or quality assurance needs. The QB4 volume booster does not have stamped gaskets, special molded diaphragm or seal parts. All parts related to normal maintenance are standard o-rings.
