ABSTRACT TO THE DISCLOSURE The gate valve has a housing hermetically joined with pipelines and a closing member which is translationally traversable in between the sealing elements of the housing. A bottom end of the closing member having a bevelled edge made so that at the instance when the pipelines get intercommunicated, the passageway is established in between the abovesaid bevelled edge, the housing and the sealing elements, said passageway growing narrow towards the direction of the flow of liquid. The above feature makes it possible to rule out the onset of conditions fraught with cavitation under the closing member and bring the cavitation outside the closing member, thereby adding to the service life of the gate valve.
