Product Description
Product Overview
This is a Lift Arm Bypass Valve (also known as Pressure Relief Valve) for construction machinery, with OEM part number P/N 7230495. It is a core pressure control component in the hydraulic system of loaders and excavators. Installed in the lift arm hydraulic circuit, it is responsible for regulating system pressure and realizing bypass pressure relief, ensuring the smooth and safe operation of the lift arm lifting and lowering actions. It is a key component to guarantee the normal operation of the hydraulic system.
Core Functions
- Overload Protection: When the hydraulic system pressure of the lift arm rises abnormally (such as full-load lifting or extreme working conditions), the valve automatically opens to relieve pressure, returning high-pressure oil to the fuel tank. This prevents the hydraulic pump, cylinder and pipeline from bursting due to overpressure, ensuring the safety of core equipment components.
- Bypass & Flow Adjustment: During the lifting and lowering of the lift arm, it accurately controls the bypass path and flow of hydraulic oil, realizing uniform and smooth control of the arm’s descent. It avoids the “sudden drop” phenomenon caused by gravity or pressure sudden changes, improving operational safety and comfort.
- Stable System Operation: Maintains the hydraulic system working pressure within the 设定 range (the marking 06-400-15 in the figure usually represents a 400bar set pressure), ensuring stable power output for the lift arm’s lifting and bearing. It eliminates equipment failure caused by pressure fluctuations.
- Ready-to-Install: 1:1 reproduction of the original factory size, thread specification and installation interface, fully matching the lift arm hydraulic circuit mounting position of the corresponding brand of loaders/excavators. No modification required, direct replacement of the original part, convenient and efficient maintenance, greatly reducing downtime.
