Key Advantages

High-Performance Materials
Body: 316SS / 304SS stainless steel. Spring: INCONEL X-750. Ball: YG6 tungsten carbide alloy. Excellent corrosion resistance and wear resistance, stable in temperatures from -50℃ to 200℃.

High Pressure & Stable Sealing
Hard-seal ball structure, rated working pressure up to 10000 PSI (68.9MPa). Passed hydrostatic test (35–135MPa / 2min) and air pressure test (0.6–0.8MPa / 2min), ensuring zero leakage under severe conditions.

Optimized Structure
Vented cap design prevents impurities from entering the grease passage. Positive flow structure improves grease injection efficiency and flow performance.

Wide Compatibility
Standard NPT connections include 1/2-14NPT, 3/8-18NPT, 1/4-18NPT. Non-standard customization is available to match various equipment requirements.

Applications
Widely used in oil extraction, natural gas transmission, water treatment and other industries for lubrication and maintenance of key valves and wellhead equipment, ensuring long-term stable operation under harsh working conditions.
