A welding device for the sealing welding of thermopolastic hoses (), includes a clamping device () with at least two clamping jaws (), of which at least one is movable and between which a hose () which is to be welded can be clamped, wherein the clamping device () has a heating devices () which is coupled to a control unit () and is configured to heat the hose clamped between the clamping jaws (). The invention is distinguished in that the at least one movable clamping jaw () is actuable with a controllable, bidirectional actuator (-) which is coupled to the control unit () in such a manner that the clamping pressure acting on the hose () can be adjusted independently of the heating device.

Welding device, use thereof as a control valve, and metering device

A filling system has a filling apparatus () and a container arrangement inserted into the filling apparatus. A main line includes a feed line (), connected to a supply container (), and a trunk line (), connected linearly downstream of the feed line (). Outside the trunk line (), at a branching point (), a branch line () branches from the main line () to a compressed-gas source (), and the main line () and the branch line (), on that side of the branching point () which is directed away from the trunk line, pass through a double-valve arrangement () having two hose-clamping valves () controlled oppositely to one another.
