The DB Speedlock consists in a body and a cover with a system of interlocking teeth made of forged material, which prevent the opening of the QOC.

The design and 3D simulation of the hinge, allows the quick unlocking and opening of the closure, through a simple rotation that allows you to “free” the teeth.
This rotation is generally manually operated by means of a gear wheel and a pinion, or by means of reducer with handwheel in case of very heavy closures

The  seal is ensured by a special custom made lip seal, in order  to adapt to different fluids and design temperatures.
Operator safety is guaranteed by the standard security lock, as described on this page.
