803278457 Solenoid Valve XCMG XDE130 Electric driving dump truck spare parts

The 803278457 solenoid valve can solve problems such as valve core jamming, malfunctioning opening and closing, internal oil leakage, failure to operate when energized, oil seepage at interfaces, high-temperature pressure relief, delayed reversing, accidental opening and closing due to bumps, circuit alarms, and oil leakage due to aging seals. It is suitable for replacing old solenoid valves, maintaining brake hydraulic circuits, original equipment manufacturer (OEM) parts, repairing hydraulic circuit reversing, and upgrading electronic control hydraulic circuits. Featuring an alloy valve body and built-in pure copper coil, it offers sensitive opening and closing, leak-proof pressure resistance, high and low temperature resistance, dust and vibration resistance, and is suitable for high-frequency reversing in engineering machinery and outdoor muddy conditions.

Core technical parameters:

– Product Model: 803278457
– Product Name: Solenoid Valve
– Material specifications: High-pressure corrosion-resistant alloy valve body, pure copper electromagnetic winding, oil-resistant composite sealing components.
– Processing technology: Original factory integrated packaging and precision machining, oil circuit honing treatment, direct installation and non-destructive adaptation of original vehicle hole positions.
– Performance and operating condition adaptability: The pressure-bearing and power-on parameters meet the standards, the opening and closing response is fast, and it is compatible with the brake hydraulic circuit electronic control reversing.
– Structural features: Integrated closed oil circuit structure, sealed and leak-proof, eliminating oil circuit pressure leakage and opening/closing failure.

This product has undergone original factory quality inspections for hydraulic circuit pressure resistance, electrical start-up and shutdown, airtightness and leak prevention, and high and low temperature durability, meeting original factory installation standards and ready to use immediately after installation. It can solve problems such as hydraulic circuit reversing failure and oil leakage and pressure relief, stabilize the on/off of the brake hydraulic circuit, optimize the electronic control braking logic, reduce fault reports, and extend the service life of brake hydraulic circuit accessories.
