Mining pipe fittings and auxiliary valves
Staple connections are indispensable components within hydraulic circuits, especially in the mining sector, where they boast an unrivaled reputation for being the premier choice in connecting and disconnecting hydraulic lines efficiently, even under the most challenging conditions. The ingenious staple design simplifies the process of connection, disconnection, and isolation of hydraulic lines, making it ideal for complex or confined applications. This technology is particularly vital in underground mining operations employing 'long wall' roof support systems, reinforcing their status as the optimal solution in demanding environments.
All Shuangfeng Our hydraulic products for underground mining are crafted to not only meet but exceed international standards, ensuring exceptional quality and reliability. Produced in a state-of-the-art ISO 9001 certified facility, our staple adaptors and hydraulic valves offer sizes from DN6 (¼") to DN76 (3"). While we provide dimensions that adhere to standard norms, we also offer bespoke customizations upon consultation with our factory, tailoring solutions to meet specific demands.
