Development of the DQL-S by our Technical Engineer: Dennis de Vries

10 January 2019

Some time ago I posted an article about our 3D printer. One of the purposes of having such a printer was to develop a standard interlock suitable to be fitted on small ball valves. This since our existing Double Key Quarterturn Interlock has a profile suitable for lever operated valves up to 8", thus this unit is of a rugged size and not suitable for very small valves.
