Valve Lapping

     Gate Valve And Ball Valve Lapping Works

               Valve Maintenance works

Lapping is the process of cleaning the control valve for maintenance purposes. The lapping is done with compounds that has roughness, and used to clean valve disc and nozzle seats etc., Every seat and disc from a relief valve or block valve, in general, must be subjected to lapping.

Valve Lapping is basically sanding down the surface of the Valves (which allow fuel and air to flow in, and exhaust to flow out) and the Head (Holds the Camshafts and valves) where they make contact with each other.

Lapping is process in GATE VALVE where Two mainly parts That is 

1. Gate DISC

2. Gate SEAT

On both face we making proper contact face by help rubbing process.

if any one parts more cuts face in running time than leakage will start.

Ball Valve Servicing----

      

 

Current buffing processes used to polish spherical balls and cups can detrimentally effect the roundness. Current machines used to polish spherical balls and cups have between 10-20% failure rate. The machine and process developed at Kemet International produces a mirror polish, holds geometry and can correct these failures while maintaining roundness down to 2 microns. The whole process takes less than 9 minutes. The system can be used on most materials including ceramic, natural metals and alloyed metals.
