Electrofluidic devices

CTEC offers solutions for fluidic applications such as compressors, pumps and valves with piezo or magnetic technologies. Piezoelectric actuators enable fine control of small flows or very high pressures. Magnetic technologies are available for higher flow rates at low pressures. Here are the main mechanisms technologies for fluidic applications:

Proportional regulation valves

Proportional regulation valves achieve very precise flow control regulation, for either flow control or pressure control. In association with a position sensor, located onto the moving part, and a cascaded position / flow control approach, CTEC provides piezo regulation valves compatible with embedded operational environments, featuring vibrations rejection onto the poppet while flowing, to warranty efficient flow control during any transient environment.

Pulse Width Modulation (PWM) valves and Pulsed Jet Actuators (PJA)

PWM valves are high frequency on / off valves. The flow control is not achieved by a position regulation of the moving part, but instead by a modulation in time and frequency of a full stroke opening. Pulsed Jet Actuators (PJA) consists in such piezo valve operation for modern application on Aircraft aerodynamics to supress drag and drift losses on aerofoils, induced by boundary layers flow separation. The PJA needs a pressure source, as an active check valve, which is an alternate approach compared to SJA which generates a pressure wave by itself.
