   SPARKLING MACHINERY NEW EC120D EC140C EC140D EC160C EC160D EC170D 17252660(14560161) Pressure Sensor is a key hydraulic monitoring component for 6 Volvo excavator models (construction/municipal use). It real-time detects hydraulic pressure, sends accurate signals to the control unit, and prevents overpressure damage. 
   Meeting Volvo OEM standards (17252660/14560161), it resists -30°C to 100°C temps, vibration, and oil corrosion, ensuring compatibility and reliability.

The Kobelco Solenoid Valve (part no. YN35V00054F1 / YN35V00052F2) is a precision-engineered hydraulic control valve designed for mid-to-large Kobelco excavators. Compatible with popular models like SK295‑9, SK350‑9, SK260‑9, SK210‑9, SK210‑8, SK140SRLC, and more, this valve delivers accurate pressure regulation, responsive hydraulic actuation, and robust performance under heavy workload conditions. Built to OEM-quality specifications with high-grade materials, it ensures long-lasting reliability and seamless drop-in replacement for both genuine and aftermarket options.

   The 56B-43-17340 Check Valve is a critical one-way flow control component for Komatsu dump trucks HD325-7/HD405-7 and articulated haulers HM300-1/HM300-2, installed in the brake piping (accumulator circuit). It prevents reverse hydraulic oil flow to maintain accumulator pressure, ensuring instant brake response and system safety.
