Valve arrangement, a method for identifying an underground valve of a valve arrangement and use of a use of valve arrangement

A valve arrangement for underground control of a fluid flow, said valve arrangement comprising:

• a valve including a valve housing containing a gate for controlling a flow of fluid through a channel arranged below the surface of the ground, wherein said gate is actuated by means of mechanical manipulation of an operating device of said valve, said operating device being coupled to said gate, and wherein said valve further comprises a valve identification tag including data regarding the specific valve type,
• an extension device comprising an extension device housing substantially surrounding an extension rod, wherein said extension rod is rotatably supported by said extension device housing, said extension rod being mechanically coupled to said operating device to enable said mechanical manipulation being performed at said ground surface, wherein said extension device further comprises a conductor extending between a valve end and a ground surface end of said extension device,
• said valve end being arranged at said valve housing and said ground surface end being arranged at the opposite end of said extension device, wherein said conductor is configured to exchange signals between an identity reading device at said ground surface and said valve identification tag to enable that said data regarding said specific valve type may be communicated to said ground surface, and
• wherein said conductor is directly arranged on or in said extension device housing.
