| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which excavator model fits cartridge relief valve 328-4314? | This mechanical screw-in safety relief valve is exclusively designed for 320D medium excavator main distribution valve block. |
| Q2 | What interchangeable short OE number corresponds to 328-4314? | The cross reference short code is 3284314, two part numbers represent the same mechanical relief valve assembly. |
| Q3 | Does this relief valve rely on electromagnetic coil to control pressure? | No, it is fully mechanical pressure limiting structure without coil, relies on spring and spool to realize automatic overflow pressure relief. |
| Q4 | What core safety function does this cartridge relief valve provide? | It limits the maximum pressure of the hydraulic main circuit, releases excess pressure to protect hydraulic pumps, pipelines and cylinder components from overload damage. |
| Q5 | What typical hydraulic faults will occur if the original relief valve fails? | Insufficient digging power, sharply rising hydraulic oil temperature, frequent oil leakage at pipe joints and easy tube burst under heavy load. |
| Q6 | What wear-resistant treatment improves the service life of valve spool? | The valve spool adopts overall carburizing hardening treatment to resist abrasion of tiny metal impurities in hydraulic oil. |
| Q7 | Is full disassembly of distribution valve required during replacement? | No, independent screw-in cartridge design, single piece can be replaced quickly without splitting the whole manifold. |
| Q8 | Is single piece sample supported for field equipment pressure test before bulk purchase? | Yes, single-piece sample order is supported to verify fitting and pressure stabilization performance on 320D excavator. |
