DD Pig Valve is a newly kind valve, which can connect two different diameter pipeline for one pipe to pigging.
DD pig valve is a patent product, and Dipper Valve owns complete independent intellectual property right.
1. DD pig valve can substitute for two ordinary pig valve, which simplify the pigging process, save operation time and sharply decrease the maintenance cost.
2. It limited the pig displacement, at the meantime, it also meet the requirement for use different size pig, which effectively guaranteed the pig launching and receiving.
3. The 90°and 180 °travel angel, provide more turning angel of the valve, ensure the continuously and stable running of the pigging working.
1. Connect Two Different Diameter Pipeline For One Pipeline For Pigging
2. Top Entry Design Valve Body
3. Stem Free From Ball Thrust Force,Stem Rotate Freely, Valve Operation Is Handy
4. Easy To Open And Close Port Cover
5. Zero Leakage
6. Interlocking Design Ensure The Safety Of Operation
7. Fire Safe Design, Fire Safe Test Meet API 6FA and API 607 Requirement
8. Cleanout Design
