Body Construction

  • Body-bonnet design is of bolted construction
  • 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 ball and the seats which can simultaneously be taken out without the need for any special maintenance tools.
  • 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 re-pressurization 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.
