Portable machine for grinding and lapping of gate valves DN 50…250 mm (2...10") PURPOSE • portable machine is designed for grinding and lapping of the sealing surfaces of the gate valve trim and wedges, globe valve and safety valve trim without their dismantling from the pipeline. ADVANTAGES ■ Grinding and lapping of the sealing surfaces of the trim directly in the pipeline without dismantling the valves from the pipeline. ■ Small weight of the unit makes it convenient for use in hard-to-reach locations. ■ The quality is achieved due to design of the working head and the mandrel, which generate complex plane parallel motion of the tool across the processed surface. ■ The set includes the wedge processing unit, replaceable discs for grinding and lapping, and a tool storage box. ■ To ensure more reliable operation, the complete set of pneumatic drive includes air preparation unit. ■ Grinding wheels on the basis of the CBN and electrocorundum ensure high productivity of the process for removing the workpiece material and have a high resistance to wear. This reduces the time of grinding and lapping, extends the life of the lapping surface.
