Built around the MAC Liquid Bullet Valve® (LBV), the Proportional Flow Controller leverages stepper motor technology to provide high precision, accurate response times and a low hysteresis, with high repeatability and low leak performance for a wide range of gases and liquids.

Proportional Flow Control enables the precise variation of gas or liquid flow rate based on the corresponding adjustment of an electrical control signal.  Two MAC valves are used to control the output pressure and these are operated by the PPC’s closed loop electronic control circuit.  Feedback is obtained from one or two transducers.   The balanced poppet, fast response and high flow of these two MAC Valves are the key contributors to the outstanding performance of the PPC.
