Air Operated Double Diaphragm (AODD) pumps require a tremendous amount of air to operate.  The most affective way to make AODD pumps more efficient is to better manage the air they consume.  The obstacle has always been that no two AODD pumps are the same, making it nearly impossible to design a product that consistently works.  A patented energy savings device has been developed called   MizAir.  The electro-pneumatic control features unique circuitry allowing it to “learn” the unique characteristics of each pump.

The QB4 closed loop electronic pressure regulator can handle flow rates as high as 200 scfm forward flow and 300 scfm exhaust flow.  It works with pressures from vacuum to 150 psig.  The unit is made up of two solenoid valves, an internal pressure transducer and an electronic control circuit mounted to an integral volume booster. Output pressure is proportional to an electrical input (command signal).  Command signals come in a choice of either a differential 0-10 Vdc or 4-20mA...

The HVC is a cost efficient regulator ideally suited for high volume, low cost, OEM applications requiring closed loop control and high forward and/or relief flow rates. The HVC can proportionally control pressure ranges up to 150 psig.

The QL3 allows high volumes of air to move quickly and precisely at pressures up to 150 psig using proportional solenoid valves with a unique analog PID circuit.  Ideal for use with flow meters, it provides high resolution and smooth pressure control at high and low flow rates and avoids the “steps” prevalent in most feed and bleed I/P’s. The output is proportional to the electrical input or command signal.
