Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the valve is used for pressure regulation rather than safety relief.
Pilot-operated valves for non-safety functions are classified elsewhere.

Import Tips & Compliance
• Include the pilot valve's set pressure and blowdown characteristics in the technical datasheet for CBSA
• Confirm the valve's compliance with API 520/526 standards for pressure relief devices
• Provide a detailed description of the pilot mechanism to distinguish it from general valves
