pilot operated, de-energized opening, compact design, IP65, DIN thread
The Riegler solenoid valves series MV1381 to MV1382 are pilot-operated diaphragm valves that work normally open. They are designed specifically for use in industrial automation and heating technology and are distinguished by their compact design, easy installation and standard-compliant connections.
As a pilot-operated valve this series needs a minimum operating pressure – without a differential pressure the diaphragm does not open. For pressureless applications the direct-acting series MV1411 to MV1415 should be specified.
