Abstract
A valve device, in particular a double stop-check valve, preferably of the two-way valve type, has at least three fluid connections () provided in a valve housing (). Two valve elements () can slide in the valve housing (). One control device () controls the valve elements (). At least one of the valve elements () forms, together with parts () of the valve housing (), a seat leak-tight closure part for the associated fluid connections ().
