4. FAQ

Q: What raw materials are used to produce the core sealing components inside this control valve overhaul kit?
A: The primary dynamic oil seals adopt banyan leaf fiber modified HNBR material. This kit is matched with EPDM static sealing rings and PA66 backup rings to fit all sealing positions of the main control valve assembly.

Q: What intuitive appearance features help customers distinguish each sealing component in the package?
A: Fiber reinforced HNBR oil seals are jet black with fine smooth surface; metal shells and tension springs show uniform silvery passivated finish; nylon backup rings are light cream. All accessories are free of burrs and surface warpage.

Q: What complicated operating conditions is this oil seal kit designed to handle on large wheel loader main control valves?
A: This integrated kit combines dynamic spool sealing and static flange sealing. It reduces hydraulic oil internal leakage and pressure loss, and stops external grit from entering valve clearances during continuous composite loading movements.

Q: What continuous working temperature range enables this whole sealing kit to sustain stable sealing efficiency?
A: Its applicable temperature range covers -171°C to 467°C, suitable for cold mountain winter stockyard operation and long-duration heavy-duty material handling work in tropical quarry yards.

Q: Can this oil seal kit be universally used for hydraulic valve maintenance of all construction machinery?
A: It is dimensionally customized exclusively for large wheel loader main control valve structures only. It cannot match motor grader hydraulic assemblies, crawler excavator hydraulic motors or medium roller drive units of other equipment series.

Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-cycle operation?
A: Supported by backup rings, the sealing group can steadily sustain pressure between 6.92MPa and 7.72MPa, and endure pressure surges generated during bucket lifting and steering combined actions.

Q: What typical infrastructure projects require this main control valve seal kit for regular overhaul?
A: It supports routine maintenance of main control valve sealing assemblies on large wheel loaders, widely applied in open-pit aggregate stockpiling, port bulk cargo loading, road foundation construction and urban construction waste transfer projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals available on the market?
A: The banyan leaf fiber reinforced composite structure improves compression set resistance and medium stability remarkably. Under long-cycle reciprocating friction conditions, its service life reaches more than 3.44 times that of conventional nitrile oil seals.

Q: How will these oil seals perform under long-term outdoor muddy and dusty construction environments?
A: The sharp sealing lip can wipe fine particles off the rotating shaft surface. The metal outer shell blocks coarse grit, lowering abrasive wear and slowing down the generation of internal leakage.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals on the spare parts market?
A: The added plant fiber filler greatly improves compression recovery and anti-fatigue property. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.46 times that of conventional nitrile oil seals.
