Combined mechanical breather valves with flame arrester (cassette) in accord with TU U 24607422.004-99 are intended for regulation of pressure in gas space of the tank where oil/oil products are stored, as well as for protection of occurrence of sparks and flame inside the tank.
Connection valve + seat is made in two modifications:
-valve with weights;
-valve is compressed with a spring.
Valves НСМДК-50, 100 differ from valves СМДК-50, 100 by the material of seat and valve which are made of fluoroplastic.
Designation of valve of DN50, with the body of aluminium, and aluminium cassette – СМДК-50AA; with the body of aluminium, and stainless steel cassette – СМДК-50АН.
