1.Preventing over - pressure damage: The relief valve is equipped with a valve mechanism. When the pressure in the hydraulic system exceeds the preset level, the valve will open, allowing the hydraulic fluid to flow back to the oil tank or other designated outlets in a controlled manner. This prevents the hydraulic system from being damaged by excessive pressure, avoiding problems such as structural damage, leaks, or even explosions.
2.Maintaining system pressure stability: It can maintain the pressure of the hydraulic system within a safe range, preventing pressure fluctuations and surges. By diverting excess hydraulic fluid, it ensures that the pressure in the system does not exceed the safe operating limit, helping to maintain the stable operation of the hydraulic system and related components.
