GROVE BT1 Top-Entry Ball Valves are manufactured in a wide range of diameters and pressure classes. In the standard versions, the valves are specified for transmission pipelines, pumping, compression and re-injection units, offshore platforms, onshore terminals, pig traps, measuring stations, and surge relief skids.

Cameron provides large diameter valves for use in natural gas, LNG, crude oil, and refined product transmission lines as well as in many other general industrial applications.

GROVE BT1 Top-Entry Ball Valves are manufactured in a wide range of diameters and pressure classes. In the standard versions, the valves are specified for transmission pipelines, pumping, compression and re-injection units, offshore platforms, onshore terminals, pig traps, measuring stations, and surge relief skids.

Cameron provides large diameter valves for use in natural gas, LNG, crude oil, and refined product transmission lines as well as in many other general industrial applications.

Standard Features

  • Size range: 1/2″ to 12″
  • ANSI Class: 150# to 1500#
  • Trunnion mounted design
  • Triple-barrier stem seals
  • Anti-blow-out stem design
  • Stem emergency grease fitting
  • Factory positioned external stops for a permanent reference to open and closed positions
  • Low friction metal-backed self lubricating PTFE sleeve bearings and thrust washers
  • Plastic polymer insert for seat sealing
  • Double-piston-effect seat rings (double sealing barrier in both directions
  • Double block-and-bleed capability
  • Pressure relief valve in the body cavity to prevent pressure lock
  • Electroless nickel coating on pressure-controlling parts and stem
  • Body thickness in accordance with ASME B16.34
  • In-line repairable
  • CE marking (PED Directive)

Optional Features

  • Self-relieving seat rings
  • Lubricated seats
  • PTFE spring energized lip seals for seat and stem sealing
  • Metal-to-metal seat sealing
  • SS or Inconel 625 overlay on sealing areas
  • Explosive decompression resistant seals (std for Class 600 and higher)
  • Anti-static device
  • Features to allow vertical installation and maintenance

Standards Compliance

  • Fire-safe in accordance with API 6FA, BS 6755 Part 2

Body Construction

  • Body-bonnet design is of bolted construction and its sizing complies with requirements given in ASME
  • VIII Div. 1
  • Bolted construction allows disassembly in-line for inspections and potential repairs
  • Removing the bonnet from 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, seating surface integrity can be assessed by pressurizing the body cavity only, before any re-pressurization of the pipeline (standard DPE design)
  • Body drain provided in the lowest part of the body cavity, featuring a, NPT drain valve with a safety plug
