Replacement of butterfly valve at AB Klaes Jansson. This weekend’s work consisted of replacing the butterfly valve at the Vitrosep treatment plant. The work is relatively simple, but still requires a lot of work. The 130 kg valve must be dismantled between the base plate and the pressure tank. Once disassembled, a new valve must be prepared. Adjustment of valve opening, installation of a new outlet and test pressure, ready for operation.
