Abstract
A gate valve has a housing provided with a passage embraced by a valve seat for a fluid medium, carrying solid particles, to flow therethrough. A gate is provided which is connected to a rod of a drive through a beam member. A hole in the beam member receives a shank with a clearance extending axially of the rod. Ends of the beam are pliable in an axial direction relative the passage and the beam ends have bevels to engage with stops of the housing. The housing has a projection to limit the travel of the gate axially of the rod.
