Abstract: A shuttle valve for a safety valve arrangement is provided with a valve housing (2), which includes a fluid inlet (4) and two fluid outlets (6, 8). A movable shut-off body (12) is arranged in the valve housing (2) and can be moved between two closure positions, in which the movable shut-off body (12) closes one of the fluid outlets (6, 8). The shut-off body (12) is arranged in a pivotably about a pivot axis (D). The shuttle valve includes a linear drive (46) which is coupled to the shut-off body (12) in a manner such that the shut-off body (12) is pivotable between its two closure positions by moving the linear drive (46).

Abstract: A safety valve has a valve seat (8) and a sealing body (12) movable relative to the valve seat (8) along a first axis (X), the sealing body being biased with a holding force (FH) along this first axis (X) in the direction of the valve seat (8). A sealing element (24) is arranged on the sealing body (12) in a manner such that with one first side (32) it can be brought into sealing contact with the valve seat (8). A pressure surface situated on a second side (34) of the sealing element (24), which is opposite to the first side (32), is connected via a pressure channel (40) to a pressure region (4) surrounded by the valve seat (8). The sealing body (12) has a contact surface (25) coming to bear on a rest surface (10) in the closed condition of the safety valve.
