### __EXCELLENT LEAKAGE MAINTAIN__

Most customers require Class IV specified in ASME B 16.104 for the allowable leakage rate for Metal Seated Ball Valves. However, DoTEC is based on the leakage rate of class VI, and it is manufactured and delivered with bubble tight (leakage 0) according to the customer's special requirements.
DoTEC uses our own special lapping machine to produce the Metal Seated Ball Valves of excellent quality with the lapping and assembly techniques of skilled workers.

### __EXCELLENT LEAKAGE MAINTAIN__
DOTEC's cryogenic ball valves have a extremely low rate of leakage.
The adjacent table shows the comparison between leakage allowances of cryogenic valves according to international standards and for critical applications. DOTEC's ball valves have one of the lowest leakage allowances in the industry. Hence DoTEC valves are ideal for critical cryogenic applications.
