The high-quality hydraulic system for Mining Applications has undergone comprehensive upgrades in flow control precision, pressure response speed, and resistance to contamination and corrosion, providing long-term safeguards for safe and intelligent mining operations. The electro-hydraulic control speed-regulating directional valve enables precise speed control of the support cylinder, ensuring smoother and more accurate movements during functions like pushing, 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 lifespan exceeding 10,000 cycles. Digital cylinders feature non-contact radar sensing for single-side installation convenience and reduced wear. Through comprehensive performance upgrades and core component innovations, the system delivers critical hydraulic power support for safe and efficient longwall operation.
