Y63B/中底压溢流阀Y-63B广泛应用于冶金、工程机械、注塑设备等工业领域，适用于需压力控制或过载保护的液压回路。其稳定性和可靠性在长期使用中得到验证，尤其适合对压力波动敏感的系统。

The Y63B Medium/Low Pressure Relief Valve is a pressure control component designed for hydraulic systems. Featuring a compact plate-mounted structure, it operates effectively in medium-low pressure conditions. The valve automatically releases excess pressure when system pressure exceeds predefined limits, ensuring equipment safety.

It offers a wide range of functions. When used as a safety valve, it remains closed under normal conditions and quickly opens to release pressure when the system pressure exceeds the set value. As a stabilizing valve, it dynamically adjusts the overflow to maintain constant system pressure. Additionally, the valve can achieve remote pressure adjustment or multi-level pressure control through its remote control port. Equipped with an unloading port, it can work with directional valves to enable circuit unloading. Its compact plate design saves installation space and is compatible with various hydraulic circuit requirements.

In terms of technical parameters, the valve has a rated working pressure that covers the medium-low pressure range, with sensitive flow regulation and fast response speed. The valve s inlet and outlet channels are optimized for fluid dynamics to reduce pressure loss. Made of wear-resistant cast iron, it is suitable for common hydraulic media such as mineral oil. The product is available in both pipe and plate mounting options, allowing users to choose flexibly according to the system layout.

The Y63B Medium/Low Pressure Relief Valve is widely used in industrial fields such as metallurgy, construction machinery, and plastic injection equipment, and is suitable for hydraulic circuits that require pressure control or overload protection. Its stability and reliability have been verified through long-term use, making it particularly suitable for systems that are sensitive to pressure fluctuations.
