1. What is this product?
This is a Solenoid Valve with the part number 1211491, specifically engineered for excavators across multiple brands and models. It is a key component in the excavator’s hydraulic system, responsible for precise control of fluid flow to enable smooth operation of critical functions.
2. Which excavator brands/models is Solenoid Valve 1211491 compatible with?
It is widely compatible with excavators from major brands (e.g., Caterpillar, Komatsu, Hyundai, Kobelco) and fits various mid-to-large-sized models. For 100% fitment accuracy:
- Provide your excavator’s brand, model, and serial number;
- Our technical team will cross-verify compatibility with OEM databases.
(Note: Common compatible models include but are not limited to CAT 320 series, Komatsu PC200-8, Hyundai R210LC-9, etc.—final confirmation requires machine details.)
3. What is the core function of Solenoid Valve 1211491?
It controls the on/off and flow rate of hydraulic fluid in the excavator’s system, directly regulating the movement of components such as the boom, arm, bucket, and swing mechanism. This ensures precise, responsive operation and stable performance in heavy-duty working conditions (e.g., digging, lifting, loading).
4. What key features make this solenoid valve reliable for excavators?
- High-Precision Control: Advanced electromagnetic coil design ensures fast response (≤ 30ms) and accurate fluid flow regulation;
- Durable Construction: High-strength aluminum alloy housing + corrosion-resistant internal components, withstands vibration, pressure (up to 350 bar), and extreme temperatures (-20°C to 120°C);
- Leak-Proof Design: Double O-ring seals and precision machining prevent hydraulic fluid leakage, reducing maintenance costs;
- Wide Voltage Compatibility: Works with 12V/24V DC excavator electrical systems (auto-adaptive to most models).
