XCMG XE2000 Excavator High-Pressure Check Valve 804009895 – A Guardian of Hydraulic Safety in Mining Equipment

Core Product Value

The XCMG original XE2000 high-pressure check valve (part number: 804009895) is precision-cast from special alloy steel, with a pressure resistance rating of 70MPa, and is specifically designed for hydraulic systems in mining equipment. It has passed both ISO 4413 and CE certifications, boasts a lifespan exceeding 1 million cycles, and offers a 60% faster response time compared to ordinary check valves, completely eliminating safety hazards such as hydraulic oil backflow and system pressure loss.

Six Major Technological Breakthroughs

🛡️ Military-Grade Structural Design

• Valve body made of 42CrMo alloy steel (tensile strength ≥1200MPa)

• Tungsten carbide coating on valve core surface (hardness HV1200)

• Seamless, integral forged structure

⚡ Intelligent Control Performance

• Zero-leakage conical seal (patent number ZL2023XXXXXX)

• Response time <8ms (industry average 15ms)

• Integrated pressure fluctuation compensator

🔧 Extreme Condition Verification

• -40℃ low-temperature opening and closing test (5000 cycles without jamming)

• Water hammer impact test (peak pressure 90MPa)

• 5000-hour salt spray corrosion test

🔄 Long-Lasting Sealing System

• Three-stage sealing structure (main seal + compensation seal + dustproof seal)

• Self-grinding valve seat design (sealing performance improves with use)

• Built-in wear limit indicator ring

📊 Digital Operation and Maintenance Interface

• Laser-engraved unique QR code

• Supports real-time pressure data monitoring

• AR disassembly and maintenance guidance system

🌪️ Environmental Adaptability

• Performance guaranteed at altitudes of 5000 meters

• Resistant to vibration level 14 (ISO 10816 standard)

• Explosion-proof electromagnetic control option
