Vertical Valve Re-Facer

To compliment the SERDI range of valve seating machines, SERDI (UK) also offer the SERDI VVR 120 Vertical Valve Re-Facer.

Serdi VVR120This machine has unmatched capability for valve stem diameters from 4 mm to 20 mm; valve head diameters up to 120 mm and seat angles from 12 to 61 degrees. Variable speed valve rotation (85 - 1000rpm) is achieved - by a patented technique - in the vertical axis, via the valve's fire face: this, combined with a variable speed grinding motor (1000 - 3000 rpm), ensures accuracy and perfect surface finish even with modern materials. The ergonomic design and a diagrammatic control board ease the setting-up and operation of this bench-top machine.

  • high precision machine with vertical valve rotation via the fire face
  • quick workpiece installation & simple adjustments with ergonomic design & fixtures
  • variable grind wheel (1000 - 3000 rpm) and valve rotation (85 - 1000 rpm) speeds for perfect surface finish even with modern materials
  • wide range of valve diameters (stems 4 - 20 mm); heads < 120mm) & seat angles (12 - 61 degrees) accommodated
