The opening / closing system of the model DB Clamplock consists in a couple of clamps (or ties) machined to allow the perfect connection of the cover to the body, in order to share the pressure load over the entire circumference of the closure.

The QOC is equipped with gear wheel and handwheel, and can also be installed at a distance in the case in which the closure is installed on devices not accessible by the operator without the use of stairs or walkways.

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 safety valve which makes possible to lock the clamps once the cover is closed.
