803278446 Plug-In Unit XCMG XDE130 Electric driving dump truck spare parts

The 803278446 plug-in unit can solve problems such as loose plug connections, poor flow, oil leakage from seals, misalignment, worn slots, stuck plugs, pressure drops, interface oxidation, stuck opening and closing, and plug failure. It is suitable for replacing old plug-in units, maintaining hydraulic valve assemblies, original equipment manufacturer (OEM) parts, modifying internal oil circuits, and repairing valve assembly plug-in seal failures. Featuring a one-piece precision-ground alloy plug-in core, composite high-pressure resistant seals, and a limit-locking structure, it ensures precise plug-in, secure locking, high-pressure leak prevention, oil resistance, and wear resistance. It is suitable for internal docking, high-frequency on/off, and high-pressure stabilizing hydraulic conditions in engineering machinery hydraulic valve assemblies.

Core technical parameters:

– Product Model: 803278446
– Product Name: Plug-In Unit
– Material specifications: High-pressure solid alloy connector body, the connector working surface is hardened and polished, and the high-frequency plugging and unplugging connection is not easy to wear and pressure loss.
– Processing technology: Precision grinding to original factory dimensions, precision machining of sealing ring groove, and non-destructive alignment and plug-in adaptation of the original vehicle valve body cavity.
– Performance and operating condition compatibility: Rated oil circuit pressure meets standards, pressure stabilization and sealing, compatible with the hydraulic main control valve group oil circuit connection control system of the whole machine.
– Structural features: Integrated limit plug structure with built-in anti-detachment limit buckle to prevent loosening due to vibration during operation and oil circuit pressure leakage.

This product has undergone high-pressure testing, plug-in verification, leak detection, and original factory quality inspection to ensure compatibility with the original vehicle valve cavity. It meets the original factory installation standards and is plug-and-play. It connects to the internal oil circuit, stabilizes the oil circuit pressure, and limits and locks the plug-in position. It is compatible with the built-in assembly of hydraulic valve groups, ensuring smooth oil circuit opening and closing and stable hydraulic operation of the entire machine.
