Transportable gate lapping machine (SL)

Portable grinding and lapping machine for the repair of sealing surfaces in gate valves and check valves, as well as on gate wedges and flanges from DN 20-2000 mm (3/4"-80").

Transportable grinding and lapping machine for repairing sealing surfaces in gate valves and non-return valves, as well as on gate valve wedges and flanges from DN 20-2000 mm (3/4"-80").

The SL's optional lapping equipment includes matching lapping wheels and lapping spindles, as well as lapping paste and accessories.

SL machines can be used universally in conventional power plants, nuclear power plants, inspection companies, refineries, chemical plants, shipyards, sugar factories, paper mills, on ships, by valve manufacturers and many more.

Advantages

Easy to operate

Low-wear tools and high-quality materials
Versatile clamping options independent of design and mounting position
Favourable price/performance ratio
Flexible use through various tool sets and accessories

Optionally extendable by:

Driven planetary discs (SLA)
to increase the removal rate and reduce the processing time (available for SL-15 and SL-2)
Digital rocker
for the exact reproduction of a once set contact pressure
Swing-Check-Adapter
for machining the sealing surfaces in non-return valve housings with large angle of inclination
VB Device
Additional arm for grinding and lapping flat sealing surfaces in valve bodies
Lapping equipment
for superfinishing or finishing the sealing surface
Special grinding wheels
for machining 3° or 5° chamfers on sealing surfaces (especially for USA gate valves)
