Cryogenic Globe Valves

FZV’s Cryogenic Globe Valves for ultra-low temperature service have been developed by FZV’s engineering team and through the investment in FZV’s cryogenic laboratory. These engineered, high-performance valves, leverage FZV’s CNC machining equipment, other speciality equipment, and clean assembly areas to ensure a consistent and high-quality product.

Key Applications

  • For application in fields such as the electric power industry, petroleum refining, petrochemical engineering, offshore oil, tap water engineering in urban construction, chemical engineering, and others.

Design Features

  • Sizes from 2” to 24”(50mm~600mm)
  • Classes range from 150-2500 CLASS
  • Operating temperature of -196℃~300℃ (the range of service temperature may vary for different materials)
  • As valves subject to a temperature ≤-101℃ shall be protected against subzero deformation, the main parts are subzero treated
  • The sealing faces of the valve seat and valve clack are hard faced with alloy to improve the erosion resistance and extend the service life of the valve
  • The friction between sealing faces is smaller during opening and closing, facilitating a longer service life
  • The valve clack is of taper, needle, ball and parabola types, and can be used to adjust the flow rate
  • SS+ graphite or metallic seal or pressure self-sealing is adopted between the valve body and bonnet for reliable sealing
  • Rising stem structure, making the valve switch position be clear at a glance
  • The valve stem thread will not come into contact with the medium, so the corrosion of medium to the thread is reduced
  • The small switching moment, reliable sealing
  • The valve clack can be machined into a parabola, spherical, needle shapes, etc. according to the requirement of the customer. It can be used for adjustment (rough adjustment) on the pipeline
  • The short stroke is suitable for application at positions subject to frequent opening
  • Y-shape stop valve – the streamline flow pass has a very high flow coefficient, and can maximally reduce the pressure drop through the system
  • By improving the structural design and selecting reasonable packing structure and qualified packing supplier, the valves can meet the Class A sealing test requirements of ISO 15848 FE
