Advantages:

  • Very short refacing time and a fast clean cut!
  • No abrasive dust!
  • Compact and handy design
  • Easy to use
  • Powered by an universal SELV (Safety Extra Low Voltage)
    power supply unit to avoid risk of electrical shock.
  • The economical solution for both on site and workshop use.

Features:

The machine is fitted with two motors providing a smooth cutting action. The operating voltage supplied to the motors by a compact power supply unit is of the low voltage type to eliminate electric hazards.
The exchangeable adapter head with the built-in slideway for cutting tool travel ensures a precise seat angle eliminating faulty setting operations.
The VDS2.3E / 2.5HD is aligned and guided by a pilot which is locked in the valve guide bore and stabilized by a supporting spider just below the valve seat.
Roundness, concentricity and surface finish of the refaced valve seat are within manufacturers’ specifications or even better.

Handling:

Setup is fast and easy.
First, lock the pilot with mounted supporting spider in the valve guide. Then, lower the machine over the pilot and position the cutting tool in front of the inner edge of the valve seat.
Turn micrometer downfeed to set the desired depth of cut. Refacing is automatic. Pressing one button is enough to start the refacing pass. Two to three passes will restore the valve seat to the original condition.
