Cryogenic Globe Valves

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
