Вопросы:
  • What materials are used in the construction of the SONGO Cryogenic Flange Check Valve?
    The valve body, ball, and stem are made from A351 CF8M (SS304), while the seat is constructed from PTFE/PCTFE for optimal sealing in cryogenic conditions.
  • Can the SONGO Cryogenic Flange Check Valve be installed in vertical pipelines?
    Yes, the swing-type design allows for unrestricted installation orientations, including vertical or inclined pipelines, though horizontal installation is typical.
  • What is the maximum pressure rating available for this valve?
    The SONGO Cryogenic Flange Check Valve is available in both 150LB and 300LB pressure ratings to accommodate various industrial applications.
  • How does the valve prevent backflow in cryogenic systems?
    The closure element operates autonomously through medium flow and force to open or close, ensuring unidirectional flow and preventing backflow, which also reduces pipeline damage from water hammer.
