Product Description:

‌The advantages and features of the Rexroth relief valve include:

‌Constant pressure relief function‌: The relief valve provides a constant flow rate in the metering pump throttling system. When the system pressure increases, the flow demand will decrease, and the relief valve will open, allowing excess fluid to overflow back to the tank, thereby maintaining a constant pump outlet pressure and ensuring the stability of the system inlet pressure. ‌

Pressure stabilization function‌: By connecting in series with the return oil line, the relief valve generates negative pressure, improves the stability of moving parts, and reduces vibration and noise. ‌

System unloading function‌: The remote control port of the relief valve can be connected in series with a small flow solenoid valve. When the solenoid valve is energized, the remote control port of the relief valve is connected to the tank, allowing the oil pump to unload, ensuring that the system can be unloaded quickly when needed. ‌

High precision and reliability‌: The Rexroth relief valve has high precision and German-made quality assurance, the positioning error of the servo drive is negligible, the dynamic response is fast, and the reliability is high. ‌ ‌

Precautions for use include‌:

‌Correctly select the type of overflow valve‌: Select the appropriate type of overflow valve according to the working characteristics and specific requirements of the hydraulic system.

The direct-acting overflow valve has a faster response and is suitable as a safety pressure-maintaining valve; the pilot overflow valve has good opening and closing characteristics and is suitable as a pressure-regulating and constant-pressure valve‌.
‌

Reasonable selection of specifications‌: Reasonably select the rated pressure and flow specifications of the overflow valve according to the working pressure and flow of the system. As a remote pressure regulating valve, the overflow valve generally has a flow rate of 0.5% to 1% of the flow rate of the overflow valve where the remote control port is located‌.

‌Correct installation and commissioning‌: Correctly use the connection method of the overflow valve and pay attention to the sealing of the connection. When adjusting the pressure, the pressure regulating mechanism should be adjusted in the correct rotation direction, and the locking nut should be fixed at the end of the pressure adjustment‌.

‌Regular maintenance‌: Regularly maintain and check the overflow valve to ensure its normal operation. Avoid using fakes to avoid affecting after-sales and repairs‌.
