They are designed to be placed in slots or grooved channel
walls and are lifted and lowered with overhead or mobile
cranes. The gate has lifting lugs for handling. The slots or
grooves are lined or fabricated from steel or stainless steel for

Bulk head gates can be used in multiple locations (slots) and
can be removed completely for storage. They cannot be
inserted when significant flows or heads are present since the
only closing force is gravity. Removal against high differential
heads is not practical or possible. A small fill or balancing gate
or valve can be installed on the bulk head gate to facilitate
head balancing and gate removal. |
