Cryogenic Ball Valves NZ
HD Process supplies cryogenic ball valves for reliable isolation and flow control in low-temperature process systems. These valves are designed for liquefied gases and other deep-cold duties requiring dependable sealing, robust construction and consistent operation.
Manual and actuated configurations are available, with valve materials, bore arrangements, bonnet designs, seals and end connections selected to suit the process medium, operating temperature and piping requirements.
Cryogenic Ball Valve Designs
Cryogenic ball valves are available in a range of configurations for process isolation, transfer and automated flow-control duties. Full-bore and reduced-bore designs can be selected according to the required flow characteristics, pipe size and pressure conditions.
- Full-bore and reduced-bore valve designs
- Manual and automated configurations
- Options for small process lines and larger transfer systems
- Valve configurations selected for the required operating duty
Extended Bonnets, Materials and Seals
Extended bonnet designs position the stem packing and operating components away from the cold zone. This helps maintain reliable stem sealing and provides space for pipe insulation around the valve body and process line.
- Standard and extended bonnet configurations
- Stainless steel and other cryogenic-compatible materials
- Low-temperature-rated valve seats and stem seals
- Material options selected for the process medium and temperature
Connections and Actuation Options
Valve end connections and operating systems can be configured to match the surrounding pipework and plant control requirements.
- Flanged connections
- Butt-weld and socket-weld connections
- Manual lever operation
- Pneumatic and electric actuator options
- Limit switches, positioners and control accessories
Cryogenic Valve Applications
Cryogenic ball valves are used where reliable shut-off and controlled flow are required in low-temperature liquid and gas systems. Typical applications include:
- Cryogenic storage tanks and transfer lines
- Liquefied-gas handling systems
- Gas processing and separation plants
- Loading and unloading systems
- Laboratory, pilot plant and test equipment
- Safety and emergency isolation points
