Hydraulic Coil

I. Product Type & Basic Specifications
This product is a plug-in solenoid valve coil with a circular design, classified under pneumatic components. It is suitable for hydraulic control systems in construction machinery and can be used as a compatible supporting component for Rexroth hydraulic equipment. The brand is FLYING BULL, supplied as 100% brand-new and genuine directly from the original manufacturer, meeting the procurement needs of wholesalers for standardized hydraulic accessories.

II. Electrical Performance & Voltage Ratings
The coil is rated for 24VDC, providing stable voltage compatibility for common 24V DC power systems in construction machinery. This ensures reliable actuation and operation within hydraulic control circuits, reducing the risk of failures due to voltage mismatch.

III. Operating Pressure
Designed for standard pressure conditions, the coil is compatible with most construction machinery hydraulic systems operating under normal pressure. It can be directly applied in general hydraulic control environments without requiring additional pressure adaptation, offering broad applicability.

IV. Maintenance Guidelines

Regularly clean the coil surface with a cloth or soft brush to remove dust and debris.

Apply lubricant as needed to minimize friction and wear.

Perform routine inspections of the coil's exterior for damage or foreign objects, and check electrical resistance and insulation to ensure they meet specifications.

Inspect seals for wear or aging and replace them promptly.

Verify that power connections, cables, and connectors are secure and intact.

When storing the coil for extended periods, keep it in a dry, well-ventilated area away from corrosive gases, direct sunlight, high temperatures, and humidity.

Always disconnect power before performing maintenance to prevent electric shock.

Regularly test solenoid valve functions, including switching response and sealing performance, to ensure long-term reliable operation of the coil.

FAQ

1,What are the core specifications of the FLYING BULL hydraulic coil (Model: R901393577), and which systems is it compatible with?

The coil is an insert-type solenoid valve circular coil classified as a pneumatic part. It operates at 24VDC (24 Volts Direct Current) and is designed for ordinary pressure working conditions, making it compatible with hydraulic control systems of construction machinery-especially suitable as a matching component for Rexroth-related hydraulic equipment. It is 100% brand-new, ensuring reliable performance for your assembly or replacement needs.

2,What maintenance measures are recommended to extend the service life of this hydraulic coil?

Key maintenance steps include: (1) Regular cleaning: Use a rag or soft brush to remove dust and debris from the coil surface, and apply lubricant to reduce friction and wear. (2) Routine inspections: Check the coil's appearance for damage/foreign objects, verify its resistance and insulation properties meet standards, inspect seals (replace if worn/aged), and ensure secure power connections. (3) Storage: When not in use long-term, store it in a dry, ventilated environment free of corrosive gases, avoiding direct sunlight, high temperatures, and humidity. (4) Safety: Always cut off power before maintenance to prevent electric shock.

3,What is the warranty period for the R901393577 hydraulic coil, and what does it cover?

The product comes with a 1-year warranty for 100% brand-new units. The warranty covers manufacturing defects that affect normal operation (e.g., coil failure due to substandard production or insulation issues). If such problems occur within the warranty period, we provide replacement or technical support in accordance with warranty terms.

4,What is the standard delivery time for bulk orders, and can expedited delivery be arranged?

The standard delivery cycle for bulk orders is 5-7 working days. For urgent needs (e.g., emergency maintenance of construction machinery), please contact our 24-hour sales team. We will adjust production and logistics schedules based on your order volume and urgency to provide customized expedited delivery solutions.

5,Does FLYING BULL offer customization services for this hydraulic coil, and what customization options are available?

Yes, we provide custom service for the R901393577 hydraulic coil. Customization mainly focuses on adapting to specific construction machinery models, such as modifying parameters to match the hydraulic system requirements of equipment from brands like Sany or Liugong. Please share your detailed needs (e.g., target machinery brand, special performance requirements) with our team to get a tailored plan.

6,As a wholesaler, can we get factory-direct pricing, and is there flexibility in minimum order quantity (MOQ)?

We offer factory-outlet pricing exclusively for wholesalers to ensure your market competitiveness. Regarding MOQ, we provide flexible terms that depend on your long-term cooperation plans (e.g., annual procurement volume) and immediate order demands. Please consult our sales team to confirm the most suitable MOQ for your business.

7,Are there any special notes for functional testing of this hydraulic coil during use?

To ensure stable operation, we recommend conducting regular functional tests on the matching solenoid valve (which includes the coil), covering two key aspects: (1) Switch response time: Verify that the coil triggers the solenoid valve to switch on/off within the normal time range. (2) Sealing performance: Check if the solenoid valve maintains good sealing when the coil is energized/de-energized, preventing hydraulic oil leakage that may affect the coil's performance.
