803278452 Shuttle Valve XCMG XDE130 Electric driving dump truck spare parts

The 803278452 shuttle valve can solve problems such as hydraulic circuit directional failure, bidirectional pressure imbalance, valve core jamming, port oil leakage, one-way pressure relief, switching lag, hydraulic circuit cross-pressure due to bumps, internal leakage due to seal wear, and failure of dual-circuit braking switching. It is suitable for replacing old shuttle valves, maintaining dual-circuit braking systems, original equipment manufacturer (OEM) parts, hydraulic circuit directional correction, and repairing bidirectional braking faults. Featuring a high-strength alloy valve body and floating reversing valve core, it offers sensitive directional control, pressure resistance, leak prevention, oil resistance, and high/low temperature resistance, making it suitable for dual-circuit braking in construction machinery and outdoor dusty/muddy conditions.

Core technical parameters:

– Product Model: 803278452
– Product Name: Shuttle Valve
– Material specifications: High-pressure forged alloy valve body, floating directional valve core, oil-resistant and anti-aging seals.
– Processing technology: Original factory precision honing of oil passages, anti-leakage machining of ports, direct installation and adaptation of original vehicle oil passage hole positions.
– Performance and operating condition adaptability: bidirectional pressure resistance meets standards, oil circuit switching is quick, and it is compatible with dual-path braking and directional pressure regulation.
– Structural features: bidirectional floating sealed structure, automatic optimal switching, avoiding oil circuit cross-pressure and switching failure.

This product has undergone bidirectional selection verification, airtight pressure maintenance, high and low temperature durability testing, and hydraulic circuit pressure resistance testing by the original factory, meeting the original factory installation standards and ready to use immediately after installation. It can eliminate problems such as hydraulic circuit pressure cross-pressure and reversing failure, automatically selects the high-pressure braking hydraulic circuit, ensures reliable dual-circuit braking linkage, avoids single-sided braking failure, and extends the service life of brake hydraulic circuit valve body components.
