The body-bonnet design is of bolted construction and its sizing complies with requirements given in ASME VIII Div. 1.
The bolted construction allows disassembly in-line for inspections and possible repairs.
Clearing the bonnet off the valve allows free access to the body cavity. A set of special maintenance tools permits the seats to be pushed back and to take out either ball and seats.
After maintenance, the valve being of standard DPE design, tightness of the seating surfaces can be assessed by pressurizing the body cavity only, before any repressurization of the pipeline.
A body drain is provided in the lowest part of the body cavity and features a NPT drain valve with a safety plug.
