 Key attribute

Product profile

• Precise Pressure Protection: As a safety valve, it automatically opens to relieve pressure when the swing system pressure exceeds the set limit. This prevents damage to the swing motor, hydraulic pump, and lines caused by overload, helping you avoid costly repairs.
• Smooth Swing Operation: By stabilizing swing circuit pressure, it effectively absorbs shock during start and stop, reduces machine shaking, and makes operation smoother and more precise for better operator comfort.
• Reliable Anti-Swing Control: The valve features an anti-swing function that helps suppress inertial sway when the swing stops, allowing the machine to position quickly and steadily for improved working efficiency.
