CRYOGENIC SERVICE

Top Entry “side ball type” Valve

For LNG service and for all applications where low temperature, liquefied medium or safe environment protection are the main focus, BREMER VALVES has designed a new “side ball type” top entry ball valve, putting together characteristics and advantages of traditional trunnion ball valves with “C” or sector valve. At the heart of this valve is the innovative “side ball design” (patent pending).

Nominal Size

1” to 10”x8”

Class

150 to 1500

Materials

  • Standard carbon steel
  • Stainless steel,
  • Duplex titanium,
  • Super duplex titanium,
  • Exotics alloys for different applications.

Features

  • Supports (trunnion) and oriented ball work against a single seat on the upstream side of the valve.
  • No body cavity inside the valve avoiding the risk of vapor overpressure due to thermal expansion and changing of phase of liquid medium.
  • Lower operating torque due to one single seat.
  • Easy and simple design, the valve can be disassembled for welding or maintenance, with no need of any special tool. Possibility to switch the inlet and outlet side of the valve with the valve already installed and welded to the line.
  • Full straight port design with no area restrictions, cavities or recesses, ensuring maximum CV, low pressure loss, no wear due to turbulence erosion or cavitation.
  • Metal spring energized seat with soft insert.
  • Seat inserts are typically made of PTFETFM or PCTFE but other materials are available upon request according to special requirements, including metal to metal tungsten or chrome carbide HVOF sprayed ball and seats.
  • Back side seat sealing by a PTFE + Elgiloy® spring energized lip seal, ensuring perfect tight and long life service in a wide temperature range from -193°C to 200°C.
  • Beside PTFE lip seal an expanded graphite ring ensures fire safe compliance.
