Filling Valve 4120004397 for Mining Equipment

The 4120004397 filling valve is a precision-engineered control solution for underground and surface mining machinery. Constructed with high-strength stainless steel (300 MPa tensile strength) and corrosion-resistant coating, it withstands continuous operation under 200-350 bar working pressure and 600-900 L/min flow capacity while maintaining IP67-rated dust and water immersion protection. The proportional control mechanism, integrated with 先导阀预卸压功能，reduces hydraulic shock during rapid oil discharge, extending equipment lifespan by 30%. Its modular hydraulic interface supports ΔP=15bar pilot pressure and DN65 flange connections, enabling seamless integration with existing mining equipment systems. The valve’s IP67 sealing and 30g 冲击耐受 design make it ideal for harsh environments with abrasive dust and water ingress.
