Abstract

A gate valve includes a housing, a first port, a second port, a passage between the ports, a valve seat formed at the passage, a closing element, which has a closure member that can be brought into sealing contact with the valve seat and has a valve stem, and a seal that cooperates with a seat. To improve the cleanability of the seal, the seat includes a closed position seat mounted on a component that is displaceable relative to the valve stem.
