Product Description


Flange connection Cryogenic ball valve is used for low temperature working condition,especially for some hazard media, such as liquidized natural gas. Applied to LNG plant, LNG receiving station, LNG gasification station and LNG carrier and ship.
 
 
Flange connection Cryogenic ball valve main parameter
Nominal diameter: DN15- DN250
Nominal pressure: 150LB- 300LB
Working temperature:-196 - +29ºC
Driving means: handle, electric actuator
Material: Stainless steel, Forged Steel , LCC/LCB, CF8/CFM8
 
Flange connection Cryogenic ball valve technology standard
Design standard: API 6D , ASME B16.34
Structural length: API 6D, ASME B16.10
Test & inspection :API 6D, API 598
Pressure and temperature:ASME B16.34
Flange ends :ASME B 16.5 , JB/T 79
The size of valve connecting flange can be designed according to customer's requirement.
 
Flange connection Cryogenic ball valve feature:
1. An extended bonnet to the valve can make the packing gland in the valve and the actuator further away from the cold process so the valve can open and close properly, protect it from freeze-damage caused by low temperature fluid.
2. Low operating torque for smoother operations.
3. Excellent seat and seal design minimizes leakage.
4. Fire-safe design.
5. Rigid body construction minimizes thermal shrinkage.
6. By adopting different materials, the cryogenic ball valve is applicable to different working temperature and medium. The minimum temperature for the ball valve is -196ºC. 
  
 Class 150~600 LB Floating Ball valve  Advantage:
1. The fluid resistance is small, its resistance coefficient with section of equal length.
2. Simple structure, small volume, light weight.
3. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system.
4. Easy to operate, open and close quickly
5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.
6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.
7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
