2PC Floating Ball Valve

I. Why Buy Floating Ball Valves Directly From Manufacturer?

Trading agents cannot fully control quality, lead time and after-sales service. Cooperating with factory enables you to track drawing confirmation, production supervision and factory test. Risk can be greatly reduced, especially for bulk project orders.


II. Factory Strength of J-VALVES Floating Ball Valves

The whole production process is completed in our own workshop: casting, machining, valve assembly, tightness test, painting and export packaging. Our workshop holds large batches of finished flanged floating ball valves ready for shipment.

  • Rich raw material stock: WCB carbon steel, A105 forged steel, SS304 / SS316 stainless steel;

  • Standard assembly line to guarantee consistent performance within same batch;

  • Independent test zone for shell & seat leakage test for every single valve;

  • Export-grade packaging: stretch film & plywood case for long ocean transportation.




III. Bulk Floating Ball Valve Project Success Stories

We have fulfilled multiple overseas municipal water & oil & gas EPC projects, delivering hundreds of flanged floating ball valves in single order. Goods arrive without rust, on-site pressure test passed smoothly, leading to long-term repeated cooperation.


IV.  Value-added Services for Buyers

Drawing verification, support for third-party inspection, material test certificates, customs documents and long-term spare parts supply.
