Cryogenic Ball Valve

Cryogenic ball valves may be used as high-efficiency shutdown valves at temperatures as low as -425 degrees Fahrenheit. These valves can also be employed in both intermittent and continuous flow scenarios. Cryogens such as oxygen, hydrogen, methane, ammonia, nitrogen, fluorine, liquefied natural gas (LNG), and deuterium are unrivaled in terms of their durability; as a result, they are used in the applications that place the greatest amount of strain on materials.

Cryogenic ball valves are ball valves that have been modified to have special properties so that they may be used at very low temperatures. The one-piece, strong stem of the cryogenic design is held together at its core by a Polyfill thrust bearing and a split ring made of stainless steel. As a direct consequence of this, it is not only risk-free to use but also generates far less friction while in use. Insulation is provided in a uniform manner using polyfill cushions. The use of an orientable stem/ball connection in conjunction with an upstream hole in the ball is what ultimately leads to the achievement of positivity.


  • Positive ball cavity relief, which consists of a relief hole bored upstream from the ball, is one method that protects against overpressure brought on by thermal expansion. 
  • On all extended stem valves with a diameter of 2 inches or bigger, the ball will always be in the right position since the stem is a single piece and includes an alignment pin.
  • When a one-piece or two-piece design is inserted inside the body, the Pressure Protected Stem from Polyfill uses thrust washers to prevent the stems from blowing out.
  • Even in the most demanding and high-cycle settings, the leak-free functioning that is guaranteed and stem-centering followers is not at all compromised.
