Abstract: Es wird eine Ventilanordnung (1) angegeben mit einem Ventil (2), das einen Durchfluss eines Warmetragermediums durch eine Warmetauscheranordnung, die eine Primarseite und eine Sekundarseite (11) aufweist, steuert und einer Ventilbetatigungseinrichtung, die ein Thermostatelement (6) aufweist, das durch eine Temperatur auf der Sekundarseite (11 ) beaufschlagt ist und durch eine Temperatur- und/oder Druckbeeinflussungseinrichtung (14) beaufschlagbar ist. Man mochte bei schneller Reaktion ein gutes Regelverhalten erreichen konnen. Hierzu ist vorgesehen, dass die Temperatur- und/oder Druckbeeinflussungsein¬ richtung (14) durch eine am Ventil (2) oder der Warmetauscheranordnung er- mittelbare physikalische Grόβe beeinflusst ist.

Abstract: The present invention relates to pressure control valve comprising: a shutter arranged in a valve chamber positioned between at least one fluid inlet and at least one fluid outlet, said shutter adapted to move relative to a valve seat defining a first opening degree of the pressure control valve;
a diaphragm being connected with the shutter, that deflects under changes in differential pressure over the diaphragm (15), thereby changing the position of the shutter with respect to the pressure responsive valve seat;
characterized in that,
a shutter guide within the valve chamber comprises a plural of contacting parts to the outer wall of the shutter positioned at its circumference.

Abstract: The invention relates to a valve arrangement (1), having a valve (2), which controls a flow of a heat-transfer medium through a heat exchanger arrangement, which comprises a primary side and a secondary side (11), and having a valve actuating device, which comprises a thermostat element (6), which is exposed to a temperature on the secondary side (11) and can be acted on by a temperature- and/or pressure-influencing device (14). The aim of the invention is to achieve good control behavior and fast reaction. For this purpose, the temperature- and/or pressure-influencing device (14) is influenced by a physical variable that can be determined at the valve (2) or the heat exchanger arrangement.

Abstract: A pressure-controlled valve (100) comprising at least one fluid inlet (101) and at least one fluid outlet (102), a pressure responsive valve seat (103), a pressure responsive valve element (104) arranged movably with respect to the pressure responsive valve seat, a diaphragm (105) which controls the position of the pressure responsive valve element with respect to the pressure responsive valve seat, and a biasing element (106) configured to bias the pressure responsive valve element in a direction away from the pressure responsive valve seat.
The pressure responsive valve element is formed with a wall (160) enclosing an internal space (170) and having a valve edge (150) forming the contact to the valve seat, where the valve seat is formed with a shape curving towards the valve edge.

Abstract: The present invention relates to a method of making a valve housing (10) for a valve (1), where the valve housing formed of a main part (11) and a cover (12), where the first
- the main part (11) is formed with an outer edge section (20) defining an inner surface and an outer surface and an opening from the externals to an inner hollow (6), where the inner surface is formed with an inner recess (23) with a first surface (22) and second surface (24) and a first contact surface (27), and where
- the cover (12) comprises a fourth surface (31) and a second contact surface (33), and where
the method comprises the steps of positioning the cover (12) inside the main part (11) such that the fourth surface (31) rests on the second surface (24) and the second contact surface (33) rests on the first contact surface (27), and where a next step is to radially compress the at least the outer part of the outer edge section (20) to a second angle where the upper and lower outer edge surfaces (30) of the cover (12) contacts the first surface (22) and second surface (24) to fix cover (12) in the position.
The present invention further relates to the first (11) and second (12) parts and to the valve housing.

Abstract: In heating and / or cooling flow systems communicating a heat transferring fluid to and from a range of heat exchanging devices where these further may be connected to loads such as for radiators, floor heating installation, heating of domestic water, cooling, HVAC, district heating systems etc., it is well known that at least one of the valves is connected to a pressure actuator comprising pressure communicating conduits, such as impulse tubes, where these include a low pressure connection and high pressure connection having a reduced orifices that tend to clog due to impurities and particles within the fluid.
The present invention overcomes this problem by introducing a dynamically changing orifice.
