Application note A061-GP99

Burner control

Bronkhorst offers mass flow meters with a close coupled motorized valve for integrated control of flows up to 5000 ln/min. Our digital D-6300 MASS-STREAM series is available with several options like a multi-functional display or additional interfaces.

In burner controls and similar applications customers need to maintain the gas supply even in case of complete power failures to avoid expensive oven shut-downs etc. The valve stays in position (= fails in place) in case of a power blackout. These applications often do not need high control speed from 'fully closed' to 'fully open' due to 365 days - 24 hour steady continuous process. So the control speed is sufficient in comparison to direct operated valves. These control valves are not shut-off valves and they are not 100% gastight.
