Proportional Flow Controller High & Low Flow – PRF Series
The TecnAir PRF Series proportional flow control valves are characterised by high performance, accuracy, linearisation, stability and provide an operationally safe design. Pneumatic control is effected via a microprocessor in which the desired control signal is specified as an analog or digital signal. A DP sensor (PE converter) measures differential pressure at an orifice gauge and sends a permanent signal as an actual value to the electronics for comparison. The latter then actuates a proportional solenoid valve to achieve a very fast, precise and proportional flow linearised with the control signal.
