In the case of mass flow control, the output signal is continuously
compared with a setpoint signal from a voltage source. Any deviations between
setpoint signal and measured signal are translated into a solenoid control
valve adjustment until the two signals are identical.
Only Bronkhorst® offers so many different models of control
valves, not just suitable up to pressures of 700 bar, but also capable
of coping with high and extremely low differential pressures, and with
high flow rates. Thanks to a modular construction the control valves can
be easily serviced.
