Key attribute

Product profile

• Critical Pressure Protection: The valve releases pressure when it gets too high, preventing damage to the pump, cylinders, travel motor, and hydraulic lines. If a relief valve is not provided, high hydraulic pressure can damage hydraulic cylinders, piping, and other components. This valve relieves excess pressure in time to protect the machine and equipment.
• Smooth and Stable Operation: By balancing the hydraulic flow entering and leaving the hydraulic cylinder, it helps control the balance of lifting and telescopic movement, making machine operation more stable and responsive. It keeps system pressure steady under different loads and working conditions.
