Frequently Asked Questions (FAQ)

1. What is the OE number and compatible fluid for this relief valve?
The core OE number is YF10-00. This valve is designed for oil media and works with standard hydraulic oils used in most conventional hydraulic systems.

2. What functions does this hydraulic relief valve perform?
It provides four key functions: constant pressure relief (maintaining set pressure), improving moving part stability (smoother operation), system unloading (releasing pressure when not needed), and overload safety protection (preventing pressure spikes).

3. What makes this relief check valve different from proportional valves?
This is a direct‑acting valve. The valve core responds immediately to pressure changes and does not require additional electronic tuning or adjustment like proportional valves. This results in faster response time and higher operating efficiency.

4. Is installation difficult for this threaded cartridge valve?
No. The threaded cartridge design fits into standard hydraulic cavities. It can be installed without modifying your existing pipeline or manifold. The large handle allows easy manual pressure adjustment on site.

5. What warranty and delivery support are offered?
The valve is 100% brand new and comes with a 1‑year warranty against manufacturing defects. Delivery takes 5–7 working days, with stable supply for wholesale stocking and regular replenishment.

6. What types of machinery is this relief valve suitable for?
It is suitable for many mobile and industrial hydraulic systems, including loaders, excavators, agricultural tractors, hydraulic presses, injection molding machines, and log splitters – any equipment that uses standard hydraulic oil and requires pressure regulation or overload protection.
