TSV SERIES
Portable grinding and lapping machine with eccentricity for the machining of sealing surfaces/nozzles in safety valves of DN ½″–12″ (15–300 mm).
The EFCO TSV utilizes a grinding movement overlaid by an additional eccentric movement. This results in a cross-hatch finish and absolutely flat sealing surface.
Suitable for use on-site and in the workshop.
