GVO MSG-44P Hydraulic Pressure Safety Rotary Motor Relief Valve Swing Valve for E307D E307C E308D KS75 Excavator Valve Parts

 Key attribute

Product profile

• Prevents Overload and Component Damage The valve serves as the primary safety device for the swing circuit. When system pressure exceeds a preset limit-whether from heavy loads, sudden shocks, or the inertia of the upper structure-it opens instantly to return excess hydraulic oil to the tank. This action prevents catastrophic damage to the swing motor, main pump, control valves, and hydraulic lines.
• Ensures Smooth and Stable Swing Operation The valve is a cartridge-type relief valve that controls the relief pressure in two stages (high and low) to ensure smooth operation. It precisely regulates pressure during swing start and stop, which eliminates the violent shaking or "pendulum" effect when the upper structure comes to a halt, significantly improving operator comfort and control precision.
