The Tianyu YF-L8H overflow valve is a high-performance pressure control device designed specifically for the safety requirements of hydraulic systems. It is suitable for hydraulic transmission systems in various fields such as engineering machinery, metallurgical equipment, mining machinery, and industrial automation.

The product features a modular structure design, with the main body made of high-strength alloy steel and manufactured through precision machining processes. The core components inside the valve have undergone special hardening treatment, allowing it to withstand a maximum working pressure of 42MPa and offering excellent wear resistance and impact resistance. The valve s flow path has been optimized to reduce pressure loss, and the cone valve sealing structure ensures faster response during opening and closing, with pressure fluctuations kept within ±2% of the rated value, meeting the requirements for high-precision pressure control.

The YF-L8H overflow valve is equipped with multiple safety features. It includes a manual adjustment knob that allows for stepless pressure setting within the range of 0.5-40MPa. The built-in pressure compensation mechanism can automatically correct pressure deviations caused by changes in oil temperature, and the specially designed damping system effectively suppresses hydraulic shock to prevent equipment damage due to sudden pressure surges. This valve is suitable for industrial equipment that requires stable pressure protection, such as hydraulic stations, injection molding machines, and hydraulic presses, especially in working conditions with frequent pressure fluctuations or long-term continuous operation.

The product has undergone rigorous factory testing and can maintain stable performance within an oil temperature range of -20℃ to 80℃. The standard configuration offers an IP65 protection rating option. Tianyu Hydraulic and Pneumatic provides comprehensive technical support for each YF-L8H overflow valve, including professional selection guidance, installation and commissioning recommendations, and maintenance and care solutions.
