Double cut-off and regulating fitting for gases has housing containing valves, valve seats and armatures with two-stage magnets

摘要

The fitting (1) has two valves (2, 3) in the cavity (6) of its casing (4), with valve plates (13, 16) and co-axial armatures (19, 20) which are axially movable. The magnetic coils (21, 22) of their two-stage magnets (25) act against the closing springs (14, 17) from the separate valve seats (8, 9). The force of the springs is taken by a support (18) back to the casing.
