2. We can do any size of the mold as per customers’ request or samples to save developing time for new items.

3. All raw materials are imported abroad to ensure production stability. 

4. We have been using the same brand and fixed models for all our raw materials to ensure stability for color, appearance and performance of each batch


5. We make high precision processing on main bodies of all our True Union Ball Valves by NC machine and ensure accuracy of functional dimensions.

6. All pilot holes of rods onto valve bodies are processed precisely to ensure sealing effect. 

7. All balls inside valves are processed by NC machine to control tolerance within 0.05mm, and then using polishing machine to grind so that they are 

    ensured smoothly-switch and leak-proof.

8. All seal rings beside balls are lathed and polishing, so they are perfectly laying on balls, with longer life span and provide good sealing effect.  

9. All sockets are processing by NC machine to be ensured coupling tight with O-Rings. 


10. Sealing experiment is processed on all finished valves to ensure them 100% qualified.
