Electro-pneumatic regulatorseries MAER200 and MAER300 |
|
|
||
| The electro-pneumatic regulator is used for continuous electronic regulation of the output pressure based on the voltage or current input signal. The outlet pressure can therefore be dynamically adapted to the requirements of the application. The valve is also equipped with an output that can be further processed. High accuracy is achieved thanks to the integrated processor and PID control. The maximum flow at an inlet pressure of 1 MPa and an outlet pressure of 0.6 MPa is up to 1500 Nl/min. for series MAER200 and up to 4000 Nl/min. for series MAER300.
