pilot operated, de-energized open, for large volumes, ATEX
The Riegler solenoid valves series MV1383 to MV1387 are pilot-operated diaphragm valves that work normally open. They are designed for use in industrial automation and heating technology and meet important standards such as ATEX and RoHS. The compact design and standard-compliant connections make integration into existing systems easy.
This series is pilot-operated and needs a minimum operating pressure to open – for pressureless applications the direct-acting series MV1411 to MV1415 is the right choice. The sealing material decides the medium and temperature.
