The Control Seal DBBV has been designed for easy maintenance. Therefore all DBBV have bottom and top entry access.

If dismantling from the bottom is preferred, check the dimension "D" for the clearance to remove the slips in the data sheet or the applicable drawing, prior to start any work.

WARNING
Do not start any work on Control Seal DBBV unless you are sure the line is depressurised. Also all line content is to be drained from valve, line, and body cavity. Failure in instructions could result in injury to personnel or cause hazardous products to be vented from the valve.

For complete instructions on installations and repair, request a copy of the Control Seal DBBV Installation and Maintenance manual.
