Abstract: A flanged valve comprising a valve box having a substantially axially extending channel formed therein, said channel at one side being adapted to be connected to a supply line and at the other side to a discharge line, while a valve means that is positioned in the valve box can shut-off the channel passage entirely or partially, and the valve box comprises means for mounting the valve box between the supply line and the discharge line, said means existing of passing-through bores through which mounting bolts can extend. In a preferred embodiment the valve box substantially forms a cylindrical flange that can have such dimensions that the valve means and its operating mechanism are positioned entirely within the valve box.

Abstract: The invention generally relates to high-pressure valves of the type having a valve passage of relatively small width, for instance in the order of 10 mm or less, and a movable valve element for opening and closing said passage. More particularly, the invention relates to an operating mechanism for moving the valve element between its open and closed position.
