Lapping and Grinding with a Compact Valve Lapping Machine

Circle Icon
The portable valve lapping machine for flat seats from EFCO Maschinenbau GmbH exemplifies our engineering expertise in the precise lapping and grinding of flat sealing surfaces for valves, valve discs, and flanges. As a lapping machine for flat sealing surfaces, it facilitates cost-effective on-site valve repair. Our experts validate the use of the EFCO VALVA series to ensure reproducible machining results.

All of our technicians are familiar with the requirements when a valve lapping machine is needed for power plants, refineries, and chemical plants. The VALVA lapping machine for flat seats is also suitable for nuclear power plants, maintenance companies, shipyards, sugar mills, paper mills, ships, and valve manufacturers.
Advantages
  • Easy operation thanks to our VALVA valve lapping machine, which we design with your practical needs in mind
  • Low-wear tools for cost-effective sealing surface machining
  • Excellent value for money thanks to our focused engineering
  • Optimal lapping results thanks to adjustable contact pressure of the grinding tools against the sealing surface
  • Exceptionally high torque, even with compact, hand-held machines
  • The VALVA-1 features an integrated reverse operation for scratch-free surface quality during lapping
Working range
  • EFCO VALVA DN 8 to DN 1600 (1/4" - 64"), validated by our experts for valve seat, mating surface, and flange sealing surface
Drive
  • Designed by our project engineers as a pneumatic-electric valve lapping machine for valve servicing, electrically rated at 230/120 V, 50/60 Hz
  • Pneumatically validated by us at 6-7 bar for valve lapping on flat-seat valves and protected by the valve body
