ZET - Model ZWP-CS -Closed Round Wall Closure

Closed round wall closure - A circular opening closure with skid tracks, model ZWP-CS. Structure: 316 stainless steel base with an integral sealing bracket (not a ring connected to the base but one part), with 316 stainless steel rails.
The closure plate is made of 316 stainless steel with sliding strips that move inside the stainless steel rails, so that the board tightens to the base only in the final section of the move, and apart from this section there is no contact between the closure and the surface. Removable brakes will be installed in the tracks to prevent the closure plate from being pulled. In the quarantine plate there is a vulcanized seal that ensures complete sealing of positive pressure and negative pressure up to a 40 meter water column.
