Ball Valves

Back to the overview

PETER MEYER Cryogenic Ball Valve

The cryogenic ball valve PM is a 1-piece, laser-welded design in 1.4404. A direction-independent integrated pressure relief system, practically no dead space, fire safe as standard, an anti blow-out stem and a pre-loaded packing seal according to TA-Luft ensure the highest possible process reliability. The cryogenic ball valves are specially designed to be used
in cryogenic process installations for very cold media such as liquefied gases CO2, N2, Ar, O2, natural gas (LNG). The spring loaded seat system assures an easy operation of
the ball down to a temperature of -200°C.
The cryogenic extension guides the stem with the packing out of the icing area.

Integrated cavity pressure relief system

  • The system relieves the overpressure inside the ball (Pt) to the upstream pressure side P1 independent of the flow direction.
  • If the medium is able to freeze, the upstream pressure must be on spring side. The spring is always on the body welding side.
  • The chambered seats remain always in contact with the ball. The system is relieving over channels between seat and body (no abrasion or dirt in the sealing surface of the seat).
  • The system is suitable for liquid and gaseous media.
  • The system is also suitable for vacuum applications.
