COAXIALLY DESIGNED, PRESSURE-COMPENSATED, DIRECTLY CONTROLLED VALVE WITH LOW PRESSURE LOSSES

摘要

A shut-off valve for controllable fluid flow may include a closing member that substantially has the structure of a hollow, round pipe, and which closing member may be pushed axially along the axis of the closing member within the valve body in order to shut off the flow of medium. The closing member may be pressed on an end face against a seat in order to shut off the flow of medium. The closing member may be directly operated with an electromagnetic lift drive.

1. A shut-off valve for controllable fluid flow, including:
a valve body; a closing member, which substantially has the structure of a hollow, round pipe, wherein the closing member is configured to be pushed axially along an axis of the closing member within the valve body in order to shut off a flow of medium and is further arranged to be pressed on an end face against a seat in order to shut off the flow of medium, such that in a shut-off state of the valve, a pressure differential acts substantially radially on a wall of the closing member, and wherein the medium is guided substantially through the closing member in an open state of the valve, and wherein the closing member is configured to be directly operated with a linear actuator, which is arranged substantially coaxially around the closing member; and one or a plurality of support ribs configured to fix the seat in the housing wherein the one or plurality of support ribs are not arranged in the direct vicinity of the seat.
