Body Construction

  • 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.
