Abstract
The invention relates to a valve device, in particular a double stop-check valve, preferably of the two-way valve type, comprising at least three fluid connections (1, 2, 3) provided in a valve housing (51), at least two valve elements (65, 67) that can slide in the valve housing (51), and at least one control device (71) for controlling the valve elements (65, 67). The valve is characterized in that at least one of the valve elements (65, 67) forms, together with parts (59/61) of the valve housing (51), a seat leak-tight closure part for the associated fluid connections (1, 2, 3).
