Abstract: The present invention pertains to an active balancing valve for a refrigeration and/or air-conditioning application. The valve comprises a valve housing (1) with an inlet orifice (11), an outlet orifice (12) and a mounting portion (13), a main valve element with a main pressure balance orifice and a control element at least partially defining a pressure balance passage. Each element is slidable inside the valve housing and comprises a control surface for controlling a fluid flow between the inlet orifice and the outlet orifice. The control element closes the main pressure balance orifice of the main valve element in a closed state of the valve.

Abstract: The invention relates to a combined valve subassembly (2) and a combined valve arrangement (1) comprising a housing (3) and such a combined valve subassembly (2). The combined valve subassembly (2) comprises a variable orifice device (4) for restricting a fluid flow throughput and a valve poppet member (6) for a passive valve unit (5). The valve seat (7) of the passive valve unit (5) is formed integral with the housing (3). The combined valve subassembly (2) has a connecting member (15, 26) that comprises a guiding member (18, 27) with a guiding surface (16) for the valve poppet member (6) and at least one fluid conduit (17) for fluidly connecting the variable orifice device (4) and the valve poppet member (6).
