Valve and use thereof in a fire-extinguishing system

Abstract

The invention relates to a valve (100) having a valve housing (3) which has a fluid inlet chamber (21) and a fluid outlet chamber (23), having a valve seat (12) which is arranged between the fluid inlet chamber (21) and the fluid outlet chamber (23), and having a closure body (50) which is movable back and forth between a release position and a blocking position, wherein the closure body (50) abuts against the valve seat (12) in a fluid-tight manner in the blocking position, and wherein the fluid inlet chamber (21) and the fluid outlet chamber (23) are connected to one another in a fluid-conducting manner in the release position. According to the invention, it is proposed that the valve seat (12) and the closure body (50) each have a sealing surface (13a,b), which are opposite one another in the blocking state, and an elastically deformable sealing element (4) which is arranged between the sealing surfaces (13a,b) in the blocking state and which completely stretches over one of the sealing surfaces.
