Cryogenic Floating Ball Valve (Liquid Nitrogen Ball Valve)
Ball valves have been widely used in low temperature and cryogenic applications, including LNG (Liquefied Natural Gas), which is now a preferred energy source. Eastern United offers reliable cryogenic trunnion-mounted and floating ball valves designed for extreme conditions.
Cryogenic Ball Valves: Product Overview
Cryogenic floating ball valves from Eastern United are engineered to operate effectively in extremely low temperatures, including those required for the handling of liquid nitrogen and other cryogenic gases.

Cryogenic Control Valve Mechanism
When closed, Eastern United’s cryogenic ball valves securely contain low-temperature gases in storage tanks. At high pressure levels, caused by extremely low temperatures, the valve opens to release pressure with controlled gas flow. Once the pressure normalizes, the valve reseals to prevent further leakage.

Liquid Nitrogen Ball Valve Overview
Eastern United cryogenic ball valves are specifically designed to manage and safely store substances at temperatures as low as -196°C (-321°F). They are capable of withstanding the resulting high pressures—up to Class 2500 or 750 psi.
These valves are commonly used in industrial applications involving:
- LNG and liquefied gases
- HVAC systems
- Food preservation
- Scientific cooling applications
Their robust design makes them ideal for transporting and handling liquefied industrial gases under the harshest conditions.
Cryogenic Ball Valve Design
Eastern United’s cryogenic ball valves consist of:
- Actuator: The external component used to operate the valve (manual or automated options).
- Stem: Connects actuator to ball and facilitates rotation.
- Ball: The floating ball that enables or blocks flow.
These valves feature extended bonnets (long stems) to keep the packing warm and prevent leaks. The extended design also allows easy integration with jacketing equipment or operation in space-constrained environments.
