High Quality Hydraulic Overflow Relief Valve For Xcmg Excavators Loaders Construction Machinery Part *******64/*******3-9150
该供应商的新产品
The *******64 / *******3-9150 Hydraulic Overflow Valve is a premium-quality, precision-calibrated safety component designed to regulate hydraulic system pressure in heavy-duty construction equipment. Installed in the main hydraulic circuit, this overflow relief valve protects sensitive components such as pumps, actuators, hoses, and control valves from damage caused by over-pressurization—ensuring both operational safety and system longevity.
Engineered to meet demanding industrial standards, this valve delivers exceptional performance in high-flow hydraulic environments, making it an ideal solution for excavators, wheel loaders, and material handling machinery working in harsh terrain.
Performance Advantages:
-
Pressure Stability: Maintains consistent system pressure by discharging excess flow once it exceeds the calibrated threshold.
-
Durable Build: Made of heat-treated alloy steel with precision-machined internals for high wear resistance and fatigue durability.
-
Responsive Flow Control: Quick-reacting internal spool minimizes hydraulic shock and prevents cavitation.
-
Long Service Life: Sealing surfaces are honed and surface-treated to withstand thousands of pressure cycles without leakage or drift.
Technical Features:
-
Operating pressure range: up to 31.5 MPa (315 bar)
-
Threaded standard BSP/NPT interface for direct installation
-
Compact body size for limited-space hydraulic manifolds
-
Maintenance-free design with factory-set cracking pressure
Cross-Compatible Equipment:Although primarily designed for XCMG excavators and wheel loaders, the valve’s standard pressure setting and port sizing allow it to be retrofitted to:
-
Komatsu PC200-7 / WA380
-
Hyundai R220LC
-
Liugong 922E, 856H
-
