Portable bench for repairing of valve sealing surfaces
Portable benches for repairing of sealing surfaces of gate valve housings
without removing them from pipelines and gate valves wedges.
High quality of the machined surface is achieved due to the design of the
machining head and making corrections, which create a complex planeparallel
movement of the tool along the processed surface.
Achievable fl atness up to 1 μm, roughness up to 0.08 microns (10..12 class).
