  • ACE cryogenic valves are widely used throughout the world, from liquefaction plants, to liquefied gas carries, receiving tank terminals as well as peak shaving plants, in a critical and hazardous service conditions down to the temperature as low as -196°
    The materials used throughout are of austenite stainless steel which maintains its strength at low temperature and the sealing system is a soft sealing, fire safe type incorporating Ke1-F ring inserts into disc which ensures trouble-fee operation.
    The metal seated removable double eccentric design is available.
    The valves are of extended bonnet design to create an insulation gas column between the plastic stem packing and the cold fluid.
    This prevents hardening and shrinking the packing and allows the external operating section of the valve remained "worm" condition.
    The valve of butt-welding end has side entry maintenance system to make the replacement of sealing ring without removing the valves from the pipes.
    All valves are tested at cryogenic temperature with "Manifold System” which can examine the performance as critical as in an actual service condition.
