Disclosed is a valve arrangement (1) for underground control of a fluid flow. The valve arrangement (1) comprises a valve (2) including a valve housing (3) containing fluid control means (4) for controlling a flow of fluid through pipe means (5) arranged below the surface of the ground (6). The fluid control means (4) is actuated by means of mechanical manipulation of an operating device (7) of the valve (2) and the operating device (7) is coupled to the fluid control means (4). The valve (2) further comprises valve identification means (8) including data regarding the specific valve type. The valve arrangement (1) further includes an extension device (9) comprising an extension device housing (10) substantially surrounding an extension rod (12), wherein the extension rod (12) is rotatably supported by the extension device housing (10). The extension rod (12) is mechanically coupled to the operating device (7) to enable the mechanical manipulation being performed at the ground surface (6), wherein the extension device (9) further comprises dedicated connection means (13) extending between a valve end (11) and a ground surface end (14)of the extension device (9).The valve end (11) is arranged at the valve housing (3) and the ground surface end (14) is arranged at the opposite end of the extension device (9), wherein the dedicated connection means (13) enable that the data regarding the specific valve type may be communicated to the ground surface (6). A method for identifying an underground valve (2) and use of a valve arrangement (1) is also disclosed. |
