Block flange manhole with hexagonal bolts up to 6/-1 bar
Product description
The block flange manhole also has a very low installation height. Based on its conically turned inside, the lid can be cleaned almost free of dead space using the CIP method. The flange can be welded on in the spherical area of the dished head. It is suitable for closures that do not need to be opened often. In addition, the screws (if properly tightened) can only be opened with a tool, which makes unauthorised opening of the cover more difficult. A further advantage is the design of the sealing. The seal sits free of dead space on the inner diameter of the flange and can be reliably cleaned during the cleaning process.
