Proportion-Air, Inc. BB1MF Pressure Control Valve

The Proportion-Air BB1MF Pressure Control Valve is a closed-loop, proportional electronic pressure regulator that converts analog command signals into regulated pneumatic output to drive downstream cylinders, valves, and tooling. Built with an aluminum body and integrated control electronics, it uses an internal pressure transducer for feedback to deliver high-precision, repeatable pressure in industrial control applications. Specifications include Brand: Proportion-Air; Manufacturer Part Number (MPN): BB1MF; output pressure range is application-specific (typically vacuum to 100+ psi depending on configuration); supply air must be clean and dry; mounting is inline or panel; control signal is an analog input. It is commonly used in automated test equipment, OEM machinery, calibration rigs, packaging lines, and process-control systems where precise and repeatable air pressure regulation is required, and it is designed for industrial manufacturing and instrumentation environments. Common replacements include Proportion-Air QB1 / QBX series electronic pressure regulators.
