Portable valve lapping machine for flat seats (VALVA)
  • Lapping machines
  • Lapping machine for flat seats (VALVA)

Portable machines for lapping and grinding of flat sealing surfaces in valves, on valve discs, flanges etc.

Wide-ranging use in conventional power stations, nuclear power stations, refurbishment companies, refineries, chemical plants, shipyards, sugar mills, paper mills, on ships, by valve manufacturers and many others.

In addition to lapping, VALVA machines are used for grinding flat sealing seats.
Advantages
  • Simple operation
  • Wear-resistant tools
  • Good price/performance ratio
  • Optimum lapping results due to adjustable contact pressure of the grinding tools against the sealing surface
  • Particularly high torque even on the compact hand-held machines
  • VALVA-1 has an integrated reversing mode to create a completely score-free surface during lapping
Working range
  • DN 8-DN 1600 (1/4" - 64")
Drive
  • electric (230/120 V, 50/60 Hz)
  • pneumatic (6-7 bar)
