QB4 High Flow Control Valve
|
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.

QL3 High Resolution Pressure Control Valve
|
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.
