Mass flow controller VEFC is ideal for the semicon industry in particular, but it is also well suited for precisely controlling inert gases virtually anywhere. The very compact VEFC extends the Controlled Pneumatics product portfolio. At the same time, it has all the advantages of piezo valves: maximum dynamic response, infinite precision, very low power consumption and heat generation and a stable flow rate without the need for manual adjustment. And all that at a very attractive price/performance ratio.
