803278452 Shuttle Valve XCMG XDE130 Electric driving dump truck spare parts

The 803278452 shuttle valve can solve problems such as oil circuit selection failure, slow differential pressure response, valve core movement, oil leakage during interconnection, valve cavity contamination, slide wear, switching jamming, bidirectional pressure relief, abnormal opening and closing noise, and selection failure. It is suitable for replacing old shuttle valves, multi-channel hydraulic maintenance, original equipment manufacturer (OEM) parts, oil circuit switching rectification, and dual-channel oil pressure interconnection repair scenarios. Featuring an integrated forged alloy valve body, floating sealing valve core, and bidirectional pressure-bearing slide structure, it offers sensitive switching, tight sealing, high-pressure resistance, oil resistance, and wear resistance, making it suitable for engineering machinery with dual-channel oil supply, differential pressure self-control, and oil circuit interlocking hydraulic conditions.

Core technical parameters:

– Product Model: 803278452
– Product Name: Shuttle Valve
– Material specifications: High-pressure thickened alloy valve body, sliding valve passage quenched and hardened, high-frequency oil circuit switching is not easy to jam or wear.
– Processing technology: original factory interconnect oil circuit precision boring, valve core high-precision matching grinding, original vehicle valve cavity non-destructive internal direct mounting adaptation.
– Performance and operating condition adaptability: Rated differential pressure meets the standard, bidirectional selective oil supply, and is compatible with the multi-channel hydraulic switching control system of the whole machine.
– Structural features: Integrated floating valve core structure, automatic differential pressure switching, eliminating oil circuit cross pressure, bidirectional oil leakage, and switching errors.

This product has undergone differential pressure calibration, bidirectional oil flow testing, high-pressure leak detection, and original factory quality inspection for compatibility with original vehicle valve chambers, meeting original factory installation standards and ready to use immediately after installation. It features intelligent optimal oil circuit flow, isolation of two-way oil pressure interference, automatic oil circuit interlocking, and compatibility with multi-way hydraulic valve groups, ensuring precise oil circuit switching and stable hydraulic operation.
