YOUR PARTNER WORLDWIDE TSV Series Grinding and Lapping Machines for safety valves DN range 15-300 mm (1/2”-12”) The EFCO TSV are portable grinding and lapping machines with eccentric. They are meant for the machining of surfaces in safety valves. The TSV-300 has two separate drives. One drive operates the grinding spindle, whereas the other drive actuates an opposite motion (eccentric motion). easy handling set-up at valves with or without flange is possible even (flat) surfaces good self-cleaning of the grinding tools => extended durability (service life) of the grinding media uniform dispersion of lapping paste during lapping procedure cross hatch TSV-300 with maschine column THE PREMIUM-PRODUCTS – MADE BY EFCO – MADE IN GERMANY

The result is a different material removal. The sealing surface inclines downwards. The use of an eccentric...
