Mining pipe fittings and auxiliary valves
Staple connections serve as essential elements in hydraulic circuits, especially within the mining industry, where they are celebrated as the top choice for efficiently connecting and disconnecting hydraulic lines, even in the most arduous conditions. The clever staple design simplifies the connection, disconnection, and isolation of hydraulic lines, making it ideal for complex or restricted spaces. This technology proves indispensable in underground mining operations with 'long wall' roof support systems, solidifying their status as the ultimate solution in challenging environments.
All Shuangfeng Our hydraulic products for underground mining are meticulously crafted to not just meet, but exceed international benchmarks, ensuring unmatched quality and dependability. Manufactured in an advanced ISO 9001 certified facility, our staple adaptors and hydraulic valves are available in sizes from DN6 (¼") to DN76 (3").
