Excavator Coil

I. Product Type & Basic Attributes
This product is a solenoid valve coil specifically designed for excavators, falling under the category of pneumatic components. It serves as a core supporting part in the hydraulic control system of excavators. The brand is FLYING BULL, with all units being 100% brand-new and genuine, supplied directly from the original factory to meet the hydraulic control requirements of construction machinery such as excavators.

II. Electrical Performance & Voltage Specifications
The product supports dual-voltage specifications, compatible with both 12V and 24V power supplies, meeting the electrical system requirements of various excavator models. Its circuitry includes essential functions such as current blocking, tuning and frequency selection, filtering, delay, and notch trapping, effectively blocking alternating current, filtering specific frequency signals, suppressing interference from signals of different frequencies, delaying current changes, and eliminating targeted frequency interference. This makes it well-suited for the complex electrical environments of excavators.

III. Dimensions & Specifications
The product features clearly defined structural dimensions, with a height (h) of 49mm and a diameter (Ø) of 22mm. Its standardized sizing ensures accurate compatibility with existing hydraulic valve components in excavators, simplifying installation and adaptation.

IV. Operating Pressure
The coil is rated for standard pressure conditions, meeting the conventional hydraulic system pressure requirements of excavators. It performs reliably in normal-pressure hydraulic control applications, ensuring stable system operation.

 

 

Frequently Asked Questions (FAQ)

1. What electrical specifications does the FLYING BULL excavator coil (TOSD‑05‑031) support, and what core functions does it have in circuits?
The coil supports dual voltage options: 12V and 24V, compatible with the electrical systems of different excavator models. Its core circuit functions include current blocking (obstructing AC, especially high‑frequency current), tuning and frequency selection (forming LC tuning circuits to screen specific frequency signals), filtering (combining with resistors/capacitors to form high‑pass/low‑pass/band‑pass/band‑stop filters), delay (delaying current changes via electromagnetic induction), and notch (eliminating specific frequency interference signals).

2. What are the physical dimensions of this excavator coil, and how does it ensure compatibility with excavator components?
The coil has standardized dimensions: height (H) 49mm and diameter (ϕ) 22mm. This fixed, precise size allows it to fit accurately with existing hydraulic valve assemblies of most excavators, minimizing installation adaptation difficulties for your maintenance or assembly needs.

3. Does FLYING BULL offer customization services for this excavator coil, and what customization scopes are available?
Yes, we provide custom service for the TOSD‑05‑031 coil. Customization mainly targets adaptation to specific excavator models – for example, adjusting parameters to match unique hydraulic system requirements of certain excavator brands. Please share your detailed customization needs (e.g., target excavator model, special performance requirements) with our team for a tailored plan.

4. What working pressure condition is this excavator coil designed for, and is it suitable for most excavator hydraulic systems?
The coil is engineered for ordinary pressure working conditions, which aligns with the conventional pressure requirements of hydraulic systems in most excavators. It can operate stably in standard hydraulic control scenarios, ensuring reliable performance without additional pressure adaptation modifications.

5. As a wholesaler, can we get factory‑direct pricing, and what flexibility is there for minimum order quantity (MOQ)?
We offer factory‑outlet pricing exclusively for wholesalers, ensuring your cost competitiveness in the market. Regarding MOQ, we provide flexible terms – specifics depend on your long‑term cooperation plans (e.g., annual procurement volume) and immediate order needs. Please consult our sales team to confirm the most suitable MOQ for your business.

6. What are the symptoms of a failing excavator solenoid coil?
Symptoms include: valve does not shift (no click when energized), slow or erratic valve response, coil housing hot to the touch (overheating), visible cracks or melting on the coil, and intermittent machine operation (valve works sometimes, not others).

7. How do I test an excavator solenoid coil with a multimeter?
Set the multimeter to ohms (Ω). Disconnect the coil from power. Measure resistance across the two terminals. Compare to the manufacturer's specification (typically 2‑20 ohms). Zero ohms = short circuit. Infinite ohms = open circuit (broken wire). Out‑of‑spec resistance = faulty coil.

8. Does the excavator coil come with a warranty?
Yes. Flying Bull provides a 1‑year warranty against manufacturing defects. Damage caused by overvoltage, incorrect installation, moisture ingress, or physical damage is not covered.

9. Is this coil a direct replacement for the original TOSD‑05‑031 part?
Yes. The TOSD‑05‑031 is manufactured as a direct replacement for the original excavator solenoid coil. It matches the original voltage options (12V/24V), dimensions (H49mm × Ø22mm), mounting, and connector type. Always verify your original part number before ordering.

10. Can this coil be used on other construction machinery besides excavators?
The TOSD‑05‑031 is specifically designed for excavators. It may be used on other construction machinery (loaders, dozers) that use the same coil specifications. Always verify compatibility with your original part number and machine model before ordering.
