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.

Abstract: A terminal valve having a cone (9) that communicates with a valve seat (10) of a seat ring (19) and cooperates with a veil (12) to control flow. The valve seat (10) and the veil (12) together form a sealing element, which seals against the cone (9) as well as the valve body (1). The cone (9) has a cylindrical portion (46) with slits (49, 50) that form a flow passage area which allows a flow that corresponds to a modified logarithmic function.

Abstract: The description relates to a device for the regulation of the amount of a medium in a heating or cooling system, comprising a combined valve, which in one and the same valve housing includes one part for pressure difference regulation (2) and one part for flow limitation (3), the flow being limited in a stepless, adjustable way, i.e. the device obtaining an adjustable Kvs-value. Also, the chosen Kvs-value can be limited by a plunger, which always can operate with its complete stroke length.

Abstract: A device for coordination of installation components of a heating or cooling system. The device includes a number of distributors (3) with functional components (5). The distributors are mounted in a profile (4), which is fixed in a complete installation unit (1). The profile (4) provides the distributors with a rotational mounting position and facilitates subsequent servicing of the installation components or installation of additional distributors to supplement the installation unit.

Abstract: The present invention relates to a device, designed to regulate the flow of a medium in a heating or cooling system, and it relates to a regulating valve (51) with a fastened mounted veil (14), which cooperates with a rotatable cone (11), which is machined and profiled, the complete valve obtaining a function, which implies, that its Kv-value can be changed within the same valve dimension, and that the flow characteristic is maintained irrespective of the changed Kv-value. The Kv-value of the valve can be changed or adjusted also subsequent to the mounting of the valve in an installation.

Abstract: A device for a flow regulation and a measurement of a medium in a heating or cooling system, which device comprises a multifunctional valve, which comprises a collector (1) with measuring outlets and an adapter for discharge and which is mounted jointly with a flow control part (2), the one part being rotatable in relation to the other part but locked in an axial direction.

Abstract: The present invention relates to a die-casting brass alloy having a dezincification resistance, which is lower than 100 &mgr;m for a separate value according to British Standard BS 2872 in a die-casting condition (i.e. without a subsequent phase transforming heat treatment). The alloy according to the invention is characterized by the following composition: Cu: 63.6 weight-% Pb: 1.8 weight-% Si: 0.73 weight-% Al: 0.07 weight-% As: 0.06 weight-% Ni: 0.2 weight-% Sn: 0.3 weight-% Fe: 0.25 weight-% B: 8 ppm Other impurities: max. 0.3 weight-% Zn: remainder.
