Autoclave CPB12 Ball Check Valve
NPT Threaded, pressures to 15,000 psi
Prevent reverse flow where leak-tight shut-off is not mandatory. When differential pressure drops below cracking pressure, valve closes. With all-metal components, valve can be used up to 650F. NOT FOR USE AS RELIEF VALVE.

Notes:
- All dimensions for reference only and subject to change.
- NPT threads must be sealed using a high quality PTFE tape and/or paste product. Refer to thread sealant manufacturer’s instructions on how to apply thread sealant.
- Sealing performance may vary based on many factors such as pressure, temperature, media, thread quality, thread material, proper thread engagement and proper use of thread sealant.
- Customer should limit the number of times an NPT fitting is assembled and disassembled because thread deformation during assembly will result in deteriorating seal quality over time. When using only PTFE tape, consider using thread lubrication to prevent galling of mating parts.
- Maximum pressure rating is based on the lowest rating of any component.
