Product Overview
The KOMATSU UCJ2310A0716-0 pressure relief valve, built around the DB6K2-44/50Y valve platform, is a pilot-operated pressure control valve engineered for Komatsu hydraulic systems. It functions as the primary system safety and pressure-regulating element, limiting maximum circuit pressure by diverting excess flow to tank once the adjustable set pressure is reached. The DB6K2 series is a proven Komatsu design used across construction and mining equipment, offering stable pressure override characteristics, low hysteresis, and reliable reseating. This valve protects pumps, cylinders, and downstream components from overpressure while maintaining consistent system pressure for predictable machine performance.
