For ball valve packing rings, we exclusively use M641 specialty low-emission packing designed specifically for ball valves.

If conventional graphite packing rings are used in stock inventory, they can strongly adhere to the valve stem over time, leading to excessive operating torque and leakage issues during later use.

By adopting our low-emission packing, even after prolonged storage, the valve maintains:

Very low operating torque
Excellent sealing performance
No adhesion issues

API 622 TUV Experimental Data Report

We have optimized the design of the packing structure for floating ball valves. Based on our field experience in petrochemical applications, we found that traditional designs using O-rings plus packing material may appear more reliable but actually create potential risks.

In conventional designs, the O-ring might become the primary seal while misleading users to believe the graphite packing also functions as a main seal. However, O-rings are vulnerable to chemical corrosion. Once the O-ring fails and the graphite packing is insufficient, both sealing mechanisms may fail, making it impossible to perform secondary pre-tightening on-site.

Additionally, our tests confirmed that insufficient graphite packing consistently fails fire safety tests. Therefore, we optimized the design by removing the O-ring and relying solely on packing as the primary seal. The benefits include 100% fire safety performance, 100% low leakage, and enhanced stem strength.
