803074989 Lifting Valve Group XCMG XDE130 Electric driving dump truck spare parts

The 803074989 lifting valve group can solve problems such as lifting jamming, load slippage, sluggish reversing, valve core jamming, joint oil leakage, valve seat wear, self-locking failure, oil pressure leakage, abnormal opening and closing noise, and weak lifting. It is suitable for replacing old lifting valve assemblies, crane hydraulic maintenance, original equipment manufacturer (OEM) parts, lifting oil circuit renovation, and repairing load pressure holding failures. It integrates a forged alloy valve body, a precision-sealed valve core, and a self-locking pressure stabilizing structure, providing sensitive reversing, stable self-locking, high-pressure leak prevention, oil resistance, and wear resistance. It is suitable for lifting, jacking, load suspension, and reciprocating lifting hydraulic applications in engineering machinery.

Core technical parameters:

– Product Model: 803074989
– Product Name: Lifting Valve Group
– Material specifications: High-pressure thickened alloy valve body, valve seat hardened by quenching, high-frequency reversing opening and closing, not easy to wear and leak.
– Processing technology: Precision boring of original oil circuit holes, matching and grinding of valve cores, and direct installation and adaptation of original vehicle hydraulic oil circuit ports without damage.
– Performance and working condition compatibility: Rated lifting pressure meets standards, self-locking pressure holding, and compatible with the whole machine’s lifting hydraulic control system.
– Structural features: Integrated reversing and lifting structure with built-in anti-fall self-locking to prevent load slippage and self-weight slippage failures.

This product has undergone load testing, reversal verification, high-pressure leak detection, and original vehicle port compatibility with original factory quality inspection, meeting original factory installation standards and ready to use immediately after installation. It precisely controls the hydraulic oil flow, regulates the lifting speed of the mechanism, and locks the load’s own weight during hovering. It is compatible with lifting hydraulic systems, ensuring safe and stable lifting operations.
