摘要

A two-way seat-type valve is provided, having a valve seat (24, 25) which is arranged between a first and a second connection, and having a closure element (20, 21) which co-operates with the valve seat (24, 25), is arranged in a guide (18, 19) so as to be movable towards the valve seat or away from the valve seat, and is subjected to a control pressure prevailing in a pressure chamber (35, 36) on the side, remote from the valve seat, of the closure element. A valve of this type should also be able to exhibit good reaction characteristics with water as hydraulic fluid. For this purpose, the closure element (20, 21) is guided seallessly in the guide (18, 19).
