description

The EX-5 Main Valve Pin Cover is made of upgraded thickened high-density toughened composite material, specially optimized for the working characteristics of EX-5 series excavator main valves with frequent vibration and complex working condition switching. Compared with the original thin-wall ordinary protective caps, the wall thickness and structural toughness are comprehensively upgraded, with excellent tear resistance, impact resistance and anti-aging stability. It can maintain stable elasticity for a long time under continuous construction vibration, mud soaking and dust erosion, without hardening, deformation, cracking or falling off. The material is added with high-efficiency anti-UV and anti-aging auxiliary ingredients, and the surface is treated with reinforced anti-fouling and anti-scouring technology, which can adapt to harsh environments such as long-term outdoor sun exposure, muddy water accumulation and gravel impact.

advantages

  • Exclusive EX-5 Dedicated Size: Precisely developed according to the original installation standard of EX-5 series main valve, with reinforced snap-on structure and stable clamping force. Zero-gap fitting after installation, effectively blocking dust, muddy water and fine gravel from entering the valve pin gap.
  • Upgraded High-toughness Material: Adopts thickened composite material formula, greatly improving anti-aging, anti-fatigue and anti-tearing performance compared with original ordinary caps, adapting to long-term frequent vibration and complex outdoor working conditions.
  • Full-range Sealing & Stable Protection: Thickened full-wrapping structure completely covers the valve core pin matching gap, locks internal hydraulic grease for a long time, keeps the valve body precision fitting surface clean and lubricated, and solves common hydraulic problems such as slow response and working device jitter.
  • Strong Environmental Adaptability: Optimized anti-scouring, anti-corrosion and anti-ultraviolet performance, resisting outdoor sun exposure, muddy water soaking and construction gravel impact, suitable for all conventional engineering construction scenarios.
  • Tool-free Quick Replacement: Standard snap-on plug-and-play design without modification, fast on-site installation and replacement, effectively reducing equipment downtime and improving construction efficiency.

FAQ

  • Q1: Is this pin cover dedicated for EX-5 series excavators?
  • A: Yes, this product is an exclusive upgraded thickened model specially developed for EX-5 series original main control valves, with dedicated precise size, and cannot be interchanged with other series or other brand valve pin covers.
  • Q2: Can it be used on other old Hitachi excavators?
  • A: Not universally applicable. This pin cover is customized for the exclusive structural size of EX-5 main valve pin shaft. Other old models have different valve body structures, and mixing use will cause poor fitting, dust leakage and easy falling off.
  • Q3: When is the best time to replace the EX-5 pin cover?
  • A: Replace it in time when the original protective cap has aging hardening, cracking, elastic failure, loose clamping or frequent falling off after long-term operation.
  • Q4: Does installation require drilling or modification?
  • A: No drilling, modification or debugging is required. Original standard snap-on size, plug-and-play, firm and tight after installation, no loosening under long-term working vibration.
  • Q5: How to extend the service life of EX-5 pin cover?
  • A: Regularly clean surface dust and mud stains, avoid long-term thick mud soaking, keep the valve cabin ventilated and clean, and maintain regular hydraulic oil replacement and grease maintenance to extend the service life of the pin cover and valve assembly.
