Abstract: This invention relates to a device (1) for reducing flow noise. In order to achieve low flow noise, the device comprises inlet apertures (3) for receiving a fluid flow, and outlet apertures (7) for forwarding the fluid flow. A combined flow cross-sectional area of outlet apertures (7) receiving fluid from a single inlet aperture (3) is larger than the flow cross-sectional area of said single inlet aperture. At least one first outlet aperture (8) is arranged such that at least a portion of the fluid flow to be received from the inlet aperture (3) may advance substantially directly via it, and at least one second outlet aperture (7) is arranged such that at least a portion of the fluid flow to be received from the inlet aperture (3) may advance via it, whereby at least one second outlet aperture (7) is arranged to produce substantially around the fluid flow formed by at least one first outlet aperture (8) a fluid flow which is slower than that.

Abstract: The invention relates to controlling (3) a flow control valve (1), comprising measuring a flow at a suitable point of a flow process (5) and calculating a pressure drop across the valve by means of a C v curve of the valve, a measured valve opening σm, and the measured flow (Q m ). By means of this calculated pressure drop, a flow set point (Q sp ) and an inverse C v curve of the valve, a new valve opening (ac) providing the desired flow is calculated. The control is thus adapted to each operating point and its prevailing flow gain and linearizes the dependence between flow control and flow.

Abstract: The invention relates to a valve (1) comprising a flow channel extending between an inlet opening (5) and an outlet opening (6), a closure member (2) arranged in the flow channel, and a noise reduction device(8). In order to efficiently prevent cavitation and noise also when flow through the valve is restricted, the valve (1) comprises a flow guide member(4) which is movable between a closed position restricting flow through the openings (9) of the noise reduction device(8) and an open position where flow through the openings (9) of the noise reduction device(8) is not restricted. The flow guide member(4) is operatively connected to the closure member (2) for moving between the closed position and the open position simultaneously as the closure member (2) moves between the closed position and the open position.

Abstract: The invention relates to an attachment ring (1)for attaching an object (4) in a flow channel (2). The attachment ring (1) has a first surface (5) for contacting the object (4) and a second surface (6) for contacting a surface of a shoulder (7). An expansion member (9) expands the attachment ring (1) by pushing the ends (11, 12) away from each other when the expansion member (9) is moved into the opening (10). At least one of the second surface (6) of the attachment ring (1) and the surface (7) of the shoulder is inclined in order to wedge the attachment ring(1) between the surface (7) of the shoulder and the object (4) when the attachment ring (1) is expanded by the expansion member (9).
