The UIC | Ball Valve DN32 – Rebuild Kit contains replacement seals, seats, and O-rings for rebuilding a worn or leaking FITOK 8 mm ball valve used in VTA distillation system process lines. Restoring the valve to factory specification prevents process fluid leaks and maintains accurate flow control between distillation stages. Using OEM-compatible rebuild components ensures correct material compatibility with the solvents and heat transfer fluids used in botanical extraction. Recommended during annual preventative maintenance on VTA VKL and VKS series systems.
