    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.

    Abstract: The present invention relate to the control of a valve that enables the self-acting (differential) pressure controller to alter its set point according to a demand of the system over which it controls (differential) pressure (i.e. a control valve, to improve control ability) or the demand of the network of which part it is (i.e. to achieve better hydraulic balance) or to input from a network or a system operator.
