Hydraulic Choke Control Console

Hydraulic Choke Control Panel is used for adjusting and displaying the opening of hydraulical choke's orifice, usually it is customised in accordance with API 16D.

    Hydraulic Choke Control Console Features and Applications
  • Single/Double choke operation with an open, mild steel painted frame, this is a typical design suitable for land rig operations
  • Single/Double choke operation with 316L stainless steel fully enclosed console with doors and complete with lid if applicable. Typically this panel type is utilised in the salt-laden offshore environment
  • Single/Double wall mounted choke display and control panel with a separate HPU (Hydraulic Power Unit), ideal for maximising the valuable space within the driller’s cabin.
