   SPARKLING MACHINERY NEW D475A D475ASD D65EX D65PX D65WX 702-21-55500 Relief Valve is a core hydraulic safety component for Komatsu D475A/D475ASD/D65EX/D65PX/D65WX excavators (heavy-duty construction/mining use). It limits maximum hydraulic system pressure to prevent overload damage to pumps, hoses, and actuators. 
   Meeting Komatsu OEM standards (702-21-55500), it resists -30°C to 100°C temps, pressure fluctuations, and contamination, ensuring seamless compatibility and long-term reliable pressure protection.

   SPARKLING MACHINERY NEW BF4M1011 BF4M2011 04102401 Solenoid Valve is a core hydraulic control component for Deutz BF4M1011 and BF4M2011 excavator engines (widely used in construction, agriculture, and light mining). As the "hydraulic flow switch", it regulates the on/off and direction of hydraulic oil for engine-related functions—ensuring responsive operation of fuel injection, cooling systems, and auxiliary hydraulics during tasks like digging and material handling, while preventing oil leaks or pressure mismatches that disrupt engine performance.
   Meeting Deutz OEM standards (part no. 04102401), it endures -30°C to 95°C temperatures, resists oil corrosion and vibration, and guarantees stable electromagnetic control. Strict testing ensures seamless compatibility with the two Deutz engine models and long-term hydraulic system reliability.
