High-quality hydraulic components have undergone comprehensive upgrades in flow control precision, pressure response speed, and resistance to contamination and corrosion, establishing robust long-term safeguards for safe and intelligent mining operations. Electro-hydraulically controlled speed-regulating directional valves enable precise speed control of support cylinder operations, ensuring smoother and more accurate movements during functions such as advancing, coal discharge, and rib protection. The 3150L/min pneumatic safety valve is China's first pillar safety valve certified for over 2000L/min, enhancing pillar impact resistance with a service life exceeding 10,000 cycles. Digital cylinders employ non-contact radar sensing for single-side installation convenience, with contactless operation minimising damage risks. Through comprehensive performance upgrades and core component innovation, the system delivers critical hydraulic power support for safe and efficient longwall operation.
