Supplier's note

1. Technical Breakthroughs:

   • Cast Iron Construction: Outperforms aluminum in pressure resistance by 20%, ensuring longevity in harsh environments.
   • Solenoid Integration: Enables 20% faster response times than manual-only valves.
   • Compact Design: Reduces spatial requirements by 15% compared to legacy models.

2. Version Selection Guide:

   • Base Model: Ideal for standard construction machinery (e.g., excavators) with routine pressure demands.
   • Advanced Model: Suitable for high-pressure applications like mining equipment, leveraging its 345 bar rating and heat-treated alloy for extreme durability.
   • Pro Model: Best for offshore or chemical processing systems requiring corrosion resistance (stainless steel) and ultra-high pressure tolerance.

With the Pro version’s 390 bar rating—30% above industry benchmarks—you can safely handle high-stress scenarios like deep-sea drilling. Pair its stainless steel body with automated control systems for zero downtime in corrosive environments.

Note: Comparative values assume industry-standard benchmarks for hydraulic relief valves.
