Silicon carbide is one of the hardest abrasives known and the particles are especially sharp. Moreover they are brittle and tend to break up into smaller particles that still retain their sharpness and so continue to work efficiently. Use for grinding, lapping and seating valves in automotive, agricultural, garden and marine engines and for oilfield and other general engineering applications.

Always consult manufacturer’s handbook/manual before commencing any operation and follow instructions given fully. The above is supplied for information and is based on laboratory and practical experience.

Directions for Use of Chemico Valve Grinding Paste

Always consult manufacturer’s handbook/manual for instructions and follow these carefully.
Otherwise for seating valves:

  1. Apply a small amount of paste to valve seat
  2. Avoid contact of the grinding paste with the valve stem and guide
  3. Grind the valve in the normal manner until a uniform seat of the desired appearance is obtained
  4. If the seat is badly pitted, first use a coarser grade paste then trim with the fine grade
  5. When a satisfactory seat has been obtained, clean off well and degrease with a suitable degreaser before valve reassembly
The coarser the grit the harsher the grind, i.e. more scoring
