Abstract: An explosion-proof valve (1), particularly a flap valve (1), for interrupting a flow of fluid (F), particularly in a pipeline, and comprising a valve housing (3) that has a passage opening (4) for the passage of the flow of fluid (F), and a valve seat (5) arranged at the passage opening (4), as well as a closing element (6), particularly a flap plate (6), which comprises a sealing surface (9) and lies with the sealing surface (9) against a valve seat (5) when in a closing position. The closing element (6) is moveably mounted on a bearing (17, 17?) in the valve housing (3). The bearing (17, 17?) of the closing element (6) is designed such that the closing element (6) can be moved, in a closing direction, out of the operating position and into the closing position by rotational and linear movement.

Abstract: An explosion-proof sliding gate valve (1) for blocking a fluid flow (F) in a pipeline, which comprises: a sliding gate valve housing (2), a sealing plate (3) which is movably mounted in the slide gate valve housing (2) between an operating position (B) and a closed position (S), wherein in the closed position (S) the sealing plate (3) blocks the fluid flow (F), a mechanism for moving the sealing plate (3) from the operating position (B) into the closed position (S), and at least one deformation body (4) for damping movement of the sealing plate. The deformation body is arranged, according to the invention, at the side between sliding gate valve housing (2) and sealing plate (3).
