Hydraulic Relief Check Valve

I. Type & Basic Specifications
This product is a hydraulic directional flow-pressure reversing valve with integrated pilot relief valve functionality. Classified as a solenoid valve, it is branded FLYING BULL and supplied as 100% brand-new and genuine directly from the original factory. Designed to operate with oil as the medium, it serves as a key component for directional, flow, and pressure control in hydraulic systems, meeting wholesalers' procurement needs for multifunctional hydraulic control accessories.

II. Operating Pressure
The valve is designed for standard pressure operation, compatible with conventional hydraulic system pressure conditions. It can be installed and used directly without requiring additional pressure adaptation. After installation, the opening pressure can be adjusted to match the system's preset value, enabling flexible pressure control for different hydraulic applications and lowering the threshold for customer use.

III. Installation Guidelines

Selection & Compatibility: Before replacement, confirm the pressure, flow, and other relevant parameters of the existing relief valve in the system. Select the appropriate valve model based on these parameters to ensure compatibility with system requirements.

Directional Alignment: When installing the new valve into the hydraulic system mounting hole, ensure its orientation matches that of the original valve to guarantee proper operation.

Fastening Specification: Use a wrench or socket wrench to tighten nuts or bolts according to the specified torque values. Under-tightening may cause leaks, while over-tightening can damage components.

Connection & Testing: After installation, reconnect all pipelines and fittings. Start the hydraulic system and observe the valve's operation. Adjust the opening pressure to the required set value if necessary.

 

 

FAQ 

1,What parameters should be confirmed when selecting this valve for a hydraulic system?

Before replacement or selection, you must confirm the pressure and flow parameters of the relief valve currently used in the target hydraulic system. Selecting a valve that matches these two core parameters ensures the valve can integrate smoothly with the system and avoid malfunctions caused by mismatching.

2,What is the warranty period for this valve, and what does it cover?

The 100% brand-new product comes with a 1-year warranty. The warranty covers manufacturing defects that affect normal operation, such as oil leakage due to insufficient fastening (caused by substandard valve body craftsmanship) or pressure control failure due to faulty internal components. If such issues occur within the warranty period, we provide replacement or technical support.

3,What is the standard delivery time for bulk orders, and is expedited delivery available?

The standard delivery cycle for bulk orders is 5-7 working days. For urgent needs (e.g., emergency maintenance of your customers' hydraulic equipment), 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.

4,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 based on your long-term cooperation plans (e.g., annual procurement volume for hydraulic parts) and immediate order demands. Please consult our sales team to confirm the most suitable MOQ for your business.

5,Does FLYING BULL provide customization services for this valve, and what customization options are available?

Yes, we offer custom service for this valve. Customization mainly focuses on adapting to specific equipment models (e.g., Hitachi, Sandvik machinery) or adjusting core parameters (such as flow control range or pressure adjustment limits) to match the unique requirements of your customers' hydraulic systems. Please share detailed needs with our team for a tailored plan.
