C5000 Cryogenic Valve Series
Compact tube-end vacuum jacketed valves for cryogenic liquid service
Key Features
- OD tube end connections — ¼" and ½" tube ends for direct connection to tube-based VJ piping systems; eliminates the need for pipe-to-tube adapters
- Compact body design — smaller overall envelope than the C2000, suited for tight installations and space-constrained valve assemblies
- In-line serviceable stem assemblies — stem, seat, and packing replace without removing the valve body from the pipeline
- Actuator adapter kit available — separate adapter kit enables pneumatic NC/NO, solenoid, and actuated-with-positioner operation
- Flow plugs available — equal percentage or linear trim available as a factory option for flow control applications
- Globe and right angle body styles — both configurations available in ½" tube; globe available in ¼" tube
- Oxygen service available — CGA G-4.1 cleaning; specify with order
Compatible Fluids
All cryogenic liquids. Series selection is based on connection type (tube vs pipe) and size, not fluid compatibility.

⚙ C5000 Actuator Adapter Kit
The C5000 Actuator Adapter Kit enables pneumatic NC/NO, solenoid, and actuated-with-positioner operation of C5000 series valves. The kit attaches to the standard C5000 manual valve body without modification.
Part number: Available as a separate item — contact Cryocomp for kit ordering information.

C5000 vs C2000: The C5000 uses OD tube ends (¼″ and ½″) while the C2000 uses IPS pipe ends (½″ to 2″). If your system uses pipe connections or requires sizes above ½″, see the C2000 Series. Both series support solenoid, positioner, and flow plug options.
