The solenoid cse is designed to contin the possible explosion which could be cused by the presence of the gs mixture inside the housing, thus voiding dngerous propgtion in the externl environment. H nd LH vlves re SIL complince with IE 658 (TÜV certified) - see section 3. They re lso designed to limit the externl temperture ccording to the certified clss to void the self ignition of the explosive mixture present in the environment. These solenoids re pplied to hydrulic vlves for ppliction in explosionhzrdous environments.
