  • Insert for dynamic flow control
    Patent number: 7066200
    Abstract: An insert for being mounted in a valve housing (80) or a tubular member for dynamic flow control of a flowing medium. The insert comprises:—a first cup-shaped part (1) provided with an outflow area;—a second cup-shaped part (10) arranged axially displaceably within the first cup-shaped part (1) and provided with an inflow area;—a pressure spring (30) arranged for exerting a force (F) that seeks to force the two cup-shaped parts (1, 10) away from each other. The second cup-shaped part (10) is configured such in relation to the first cup-shaped part (1) that the inflow area of the first cup-shaped part (1) is closed in response to a displacement of the second cup-shaped part (10) in relation to the first cup-shaped part (1).

  • Differential pressure valve for controlling a system having a heat carrying medium
    Patent number: 6058955
    Abstract: The invention relates to a differential pressure valve for the control of a plant with a heat carrying medium. The differential pressure valve has a membrane controlled by a differential pressure for the regulation of the flow of the heat carrying medium between an inlet and an outlet, an adjustable closing member between the inlet and the membrane, one or more fixed openings, the areas of which can be changed linearly by the closing member, one or more variable openings, the areas of which are changed by the membrane, and electrically activated members for closing one of the variable openings or fixed openings by force or by time control independently of the flow in the valve. The invention is configured as parts to be inserted in a known differential pressure valve without dismounting it in such a plant.
