Abstract (en)

[origin: EP0764803A1] The valve has two independent shut-off elements (22,22'), which are positioned axially movable on the actuating tappet (35). The tappet ends (42,42') projecting over the elements carry a gas-proof compensation wall (43). This is at least partially formed by a flexible diaphragm (46), and is fastened on the valve housing side. The wall, and a facing charging surface (34) of the neighbouring shut-off element, form movable determinating walls for compensation chambers (44). These are for compensation of fluid pressures engaging on the actuating tappet. The two walls are connected to the consumer channel (11) via branch channels (53).
