    • Device for flow control of a medium in a heating or cooling system where the device is a complete regulating valve (1), with a valve body (2) comprising an inlet connection (3), an outlet connection (4), a valve neck (5) in which a valve seat (6) and a flow through opening (7) are provided. In the valve neck (5) a complete valve trim (38) and a valve hand wheel (10) are provided, and through the valve hand wheel (10) and the complete valve trim (38) a valve shaft (11) with a return spring (12) are provided. The valve body (2) comprises a first cone (13), which determine the preset of the maximal flow through the complete regulating valve (1), i.e. the Kvs-value of the valve, by that the first cone (13) has at least one opening (14) for flowing through of the medium, where the design of the opening (14) determines the regulating characteristic of the complete regulating valve (1), and where the Kvs-value of the valve is changed continuously, with maintained regulating characteristic, by that the first cone (13) is arranged continuously, axially displaceable relative the valve seat (6), whereby selected parts of the opening (14) of the first cone are shielded by the valve seat (6).
    • 用于在加热或冷却系统中介质的流量控制的装置,其中所述装置是完整的调节阀(1),其中阀体(2)包括入口连接(3),出口连接(4),阀颈 (5),其中设置有阀座(6)和流通开口(7)。 在阀颈(5)中,提供完整的阀门装置(38)和阀手轮(10),并且通过阀手轮(10)和整个阀门装置(38)具有阀轴(11) 提供复位弹簧(12)。 阀体(2)包括第一锥体(13),其确定通过完整调节阀(1)的最大流量的预设值,即阀的Kvs值,第一锥体(13)具有 用于流过介质的至少一个开口(14),其中开口(14)的设计确定完整调节阀(1)的调节特性,并且其中阀的Kvs值连续变化,并保持 通过第一锥体(13)相对于阀座(6)连续地布置成可轴向移动,由此第一锥体的开口(14)的选定部分被阀座(6)屏蔽。
