Proportional Solenoid Valve Coil

I. Product Type & Basic Specifications
This product is a solenoid valve coil, categorized under coil components. The brand is FLYING BULL, and all units are supplied as 100% new and genuine, sourced directly from the original factory. Designed to operate with oil as the medium, it serves as a compatible coil for proportional solenoid valves in oil pump systems. As a key component of construction machinery hydraulic control systems, it meets wholesalers' procurement needs for standardized hydraulic valve coils.

II. Electrical Performance & Voltage Specifications
The coil operates at a stable 12V DC, precisely matching the 12V power supply used in hydraulic control systems-such as oil pump proportional solenoid valves-in construction machinery. This ensures reliable coil activation in the circuit, reduces the risk of equipment failure due to voltage mismatch, and offers strong adaptability.

III. Operating Pressure
The coil is rated for standard pressure, making it suitable for the normal pressure conditions in most construction machinery hydraulic systems. It can be directly applied in common hydraulic control environments without requiring additional pressure adjustments, lowering the threshold for customer use and providing wide compatibility.

IV. Durability & Service Life
The product comes with a one-year warranty and is manufactured to high-quality standards, backed by over 15 years of brand production experience. Regular routine maintenance, such as periodic inspections and cleaning, can further extend its stable operating life. This helps minimize hydraulic system issues caused by coil failure and reduces after-sales replacement costs and frequency for wholesaler customers.

V. Maintenance Guidelines

Daily Inspection: Visually check the coil for any deformation, cracks, or corrosion. Ensure all connections are secure and solder joints intact. Conduct functional testing to verify there are no short circuits or open circuits.

Regular Cleaning: Periodically remove dust, oil, and other contaminants from the coil surface. Clean the housing using a cleaning solution or water, but avoid using sharp objects that could scratch or damage the coil.

 

 

FAQ 

1,What is the core application and matching medium of the FLYING BULL 12-volt solenoid coil (Model: R900021389)?

This product is a solenoid valve coil classified as a "coil" component, with 100% brand-new quality and FLYING BULL as the brand. It is specifically designed to work with oil as the medium and serves as a matching coil for oil pump proportional solenoid valves. It is a key part of construction machinery hydraulic control systems, making it ideal for your bulk supply to construction machinery maintenance providers or hydraulic equipment manufacturers.

2,What electrical specification does this solenoid coil follow, and how does it ensure compatibility with equipment?

The coil operates at a standard 12 volts, which precisely matches the 12V power supply systems of hydraulic control devices (such as oil pump proportional solenoid valves) commonly used in construction machinery. This stable voltage adaptation avoids equipment malfunctions caused by voltage mismatch, ensuring reliable triggering and operation of the hydraulic system.

3,What working pressure condition is the R900021389 solenoid coil suitable for, and does it require additional pressure adjustment?

It is engineered for ordinary pressure working conditions, which aligns with the conventional pressure requirements of most construction machinery hydraulic systems. No extra pressure adaptation or modification is needed-it can be directly installed and used in standard pressure hydraulic control scenarios, reducing the application threshold for your customers.
