PORTABLE MACHINE FOR GRINDING AND LAPPING OF STOP VALVES (PLUG VALVES) PURPOSE • portable device is designed for grinding and lapping the sealing surfaces of the plug valve trim without their dismantling from the pipeline. MACHINED-SURFACE TYPES: • sealing surfaces of the PSV and plug valve trim and spools. DN OF VALVE: • 32...200 mm (1...8″). COMPLETE SET • professional pneumatic (Atlas Copco) and/or electric (Bosch) and/or battery (Metabo) drives; • device for mounting on the middle flange and machining the gate valve wedges; • stand for spool machining; • multi-function installation device; • replaceable grinding and lapping discs; • set of self-adhesive grinding wheels; • air preparation unit with a sleeve for compressed air supply; • carrying case; • set of spindles with the abrasive wheels based on electrocorundum; • set of spindles coated with the boron nitride. 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.
