Precision-Engineered 701-40-51002 Hydraulic Safety Relief Valve for Komatsu D155 Bulldozers

2.Our facility, Donggang Die Casting Factory, is strategically located in Donggang City, China, serving as a global hub for high-grade construction machinery components. For over 25 years, we have specialized exclusively in hydraulic valves and complex die-cast parts, making us a trusted source for distributors and service providers worldwide.

Uncompromising Quality Control
Zero-Defect Casting: We employ advanced die-casting technology that achieves a component porosity rate of less than 0.5%. This metallurgical precision eliminates micro-fractures, ensuring the valve's structural integrity under extreme pressure cycles.

100% Pressure Testing: Every 701-40-51002 valve is subjected to a mandatory 100% airtightness test at 30 MPa (4350 PSI) before packaging, guaranteeing a leak-free seal and reliable system activation.

CNC Precision: Components are finished using high-precision CNC machining centers, achieving tolerances as tight as ±0.005mm for seamless integration and function within the Komatsu hydraulic system.

3. Material Integrity and Durability
Engineered for Longevity in Extreme Conditions
The demanding nature of dozers like the Komatsu D155 requires components built to outlast. Our 701-40-51002 valve features:

Advanced Metallurgy: Constructed from high-strength alloy iron with specialized surface hardening treatments.

Superior Wear Resistance: The core sealing and moving components achieve a surface hardness exceeding HRC60+, which extends the valve's service life by up to 30% compared to standard replacements.

Reliable Performance: Designed to maintain consistent pressure settings in harsh environments, including mining, heavy construction, and earthmoving operations.
