Mass flow meter manufacturer Bronkhurst High-Tech has developed a new, directly driven control valve for gas flow control up to 200 bar – the first without a Vary-P mechanism.
The company says this development makes mass flow controllers fitted with this valve even more compact, offering even faster control.
Previously these units were developed with a Vary-P mechanism. Bronkhorst introduced Vary-P control valves in 1985 for controlling high-pressure gas flow with high pressure differences of up to 400 bar – this was later extended to 700 bar.
