FORWAD AND BACK PRESSURE CONTROLLERS

The electronic Red-Y smart pressure controller combine the reliable technology of our digital mass flow controllers with electronic pressure control.

The devices automatically control a predefined process pressure and at the same time measure and/or limit the flow rate. On-the-fly switching between pressure control and flow control offers maximum flexibility.
