   SPARKLING MACHINERY NEW EC55C EC60C EC60E ECR58D ECR88D 14576751 Solenoid Valve is a critical hydraulic control component for Volvo EC55C, EC60C, EC60E, ECR58D, and ECR88D excavators (widely used in small-scale construction, landscaping, and municipal maintenance). As the "hydraulic flow regulator", it precisely controls the on/off and direction of hydraulic oil for key functions like bucket tilting, arm lifting, and auxiliary tool operation—ensuring responsive and smooth performance during light-duty tasks, while preventing oil leaks or pressure mismatches that reduce equipment efficiency.
   Meeting Volvo OEM standards (part no. 14576751), it withstands -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees stable electromagnetic switching. Strict testing ensures seamless compatibility with the five Volvo models and long-term reliability of the hydraulic system.

   SPARKLING MACHINERY NEW 301.5 302.5 303 303.5 156-8847 Solenoid is a dedicated electrical control component for CATERPILLAR 301.5, 302.5, 303, and 303.5 mini crawler excavators (versatile for landscaping, indoor demolition, and small-scale construction). As a key switch for the excavator’s hydraulic or fuel systems, it converts electrical signals into mechanical action to control valve opening/closing, ensuring precise operation of functions like bucket tilting and arm movement during delicate tasks.
   Meeting CATERPILLAR OEM standards (part no. 156-8847), it endures -30°C to 85°C temperatures, resists vibration and electrical interference, and maintains stable switching performance. Strict testing guarantees seamless compatibility and long-term reliability for the four CATERPILLAR models.

   SPARKLING MACHINERY NEW 307D 308D 311B 311C 312B 312C 111-9916 Solenoid Valve is a dedicated hydraulic-electronic control component for Caterpillar 307D, 308D, 311B, 311C, 312B, and 312C crawler excavators (widely used in construction, municipal engineering, and medium-scale earthmoving). As the "hydraulic flow switch core", it uses electrical signals to regulate the on/off and direction of hydraulic oil flow—powering precise control of boom lifting, bucket digging, and swing movements during tasks like trench digging, material loading, and site trimming, while ensuring responsive and stable equipment operation.
   Meeting Caterpillar OEM standards (part no. 111-9916), it endures 28 MPa working pressure, -30°C to 90°C temperatures, resists hydraulic oil corrosion and vibration, and maintains stable signal transmission. Strict testing guarantees seamless compatibility with the six Caterpillar models and long-term hydraulic-electronic system reliability.
