Cryogenic Globe Valves
RANGER’s Cryogenic Globe Valves for ultra-low temperature service have been engineered to ensure high-performance and leverage CNC machining equipment, as well as other specialty equipment, and dust-free/clean assembly areas to ensure a consistent and high-quality product.
Key Application(s)
- 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
