  • Patent number: 8833392
    Abstract: A regulating valve for flow control of a medium in a heating or cooling system includes a valve body including an inlet connection, an outlet connection, and a valve neck in which a valve seat and a flow through opening are provided. In the valve neck, a complete valve trim and a valve hand wheel are provided. The valve body includes a first cone to determine the preset (Kvs-value) of the maximal flow through the complete regulating valve. The first cone has at least one opening for flowing through of the medium, where the design of the opening determines the regulating characteristic of the complete regulating valve, and where the Kvs-value of the valve is changed continuously, with maintained regulating characteristic. The first cone is arranged continuously, axially displaceable relative the valve seat, whereby selected parts of the opening of the first cone are shielded by the valve seat.

  • Patent number: 8424556
    Abstract: A device for regulating the flow in a heating and cooling system. The flow is controlled by a complete valve realized as a combination of a difference pressure valve (5) and a flow controlling valve (6) where the complete valve construction allows flushing of the tube system where the valve is mounted. A first static pressure (P1) in the inlet (2), a second static pressure (P2) in the intermediate chamber (4) and a third static pressure (P3) in the outlet (3) are measured by the measuring nipples (27a, 27b) and the difference between the second and the third static pressures (P2, P3) is adjustable during operation.
