The Tianyu Hydraulic Y1-63B Medium-Low Pressure Relief Valve (Model Y163B) is designed for pressure regulation in hydraulic systems. It ensures stable system pressure by diverting excess fluid to the tank when the preset pressure is exceeded. The valve features a compact plate-mounted structure for easy integration and supports remote pressure adjustment via external control valves. Its robust construction and optimized internal components provide reliable performance under medium flow and pressure conditions. Suitable for industrial applications such as machine tools and metallurgical equipment, the valve offers consistent pressure control with minimal fluctuation. Key advantages include versatility (usable as a safety or unloading valve), durability, and straightforward maintenance. The design accommodates various hydraulic fluids, ensuring compatibility across different systems.67
