Product Overview
The Vornet API 6A Check Valve is an automatic backflow-prevention valve for high-pressure upstream oil and gas applications.
Available structural types are swing check and lift check. Medium flow opens the valve in the forward direction, while reverse flow causes closure to protect upstream equipment.
Project configuration is defined using the visible pressure range, KU temperature class, material classes AA–HH, specification levels PSL1–3 and performance levels PR1 or PR2.
- Automatic Check Action: Opens forward and closes against reverse flow.
- Structure Options: Swing and lift check types are listed.
- Upstream Protection: Intended to protect upstream equipment.
- API 6A Configuration: Material class, PSL and PR are project-defined.
