Abstract

Automatic recirculation valve for use in installations where a minimum flow is required for protecting such as centrifugal pumps. The valve includes a valve housing (13) with a plunger (12) controlled by a main flow and a spring (2). The plunger (12) is displaceable in a plunger guide sleeve (9) in the valve housing (13) and arranged to seal against a seat (14) in its one end position, in which position a bypass flow flows through a bore (18) in the plunger (12) and out through a bypass tube (7) via at least two variable constriction stations (A-C) arranged in the guide sleeve (9).
