<p>Pipe separator (1) provided with a stop device to separate an inlet side (2) from an outlet side (3). In order to prevent the stop device (4) from floating when it is within a pressure area switching the stop device, a pilot valve (10) has been provided to actuate the stop device. The configuration of the pilot valve (10) is such that the pressure required for the switching from a first passage position to a second stop position is smaller than the pressure required for the switching from the second to the first position. </p> |
