4. FAQ

Q: What diversified materials are adopted inside this hydraulic valve overhaul gasket kit?
A: This set combines stainless steel reinforced graphite composite gaskets, palm fiber sealing sheets, EPDM rubber washers and precision metal shims. Different materials are matched to various flange and cover sealing surfaces of the main hydraulic valve.

Q: What visual differences can customers identify easily among all sealing accessories inside the package?
A: Steel composite gaskets are silver-gray with graphite surface; fiber gaskets are light tan; rubber washers are matte black; adjusting shims are bright silver metal. All parts are pre-punched and cut according to original installation contours.

Q: What sealing requirements is this gasket kit designed to satisfy for ultra-large excavator main hydraulic valves?
A: It focuses on static joint sealing of valve housings and end covers. Multi-material collocation adapts to different pressure and temperature conditions to prevent hydraulic oil leakage on split mating surfaces.

Q: What continuous working temperature range can this whole gasket kit withstand steadily?
A: Its applicable temperature range covers -173°C to 465°C, suitable for cold alpine winter large open-pit mining and uninterrupted ultra-heavy cyclic excavation work at tropical quarry yards.

Q: Can this gasket kit be universally used for hydraulic valve overhaul of all construction machinery?
A: It is dimensionally customized exclusively for ultra large crawler excavator main hydraulic valve structures only. It cannot fit road grader hydraulic assemblies, wheel loader gearboxes or medium excavator pump housings of other machine series.

Q: What static working pressure can these composite gaskets endure during long-term continuous operation?
A: The matched combination can steadily sustain static pressure ranging from 6.92MPa to 7.73MPa. It maintains reliable sealing even when slight housing deformation occurs under ultra-heavy load.

Q: What typical large-scale engineering projects need this main hydraulic valve gasket kit for regular maintenance?
A: It is used for routine overhaul of main hydraulic valve assemblies on ultra large crawler excavators, widely applied in super large open-pit mineral exploitation, coastal land reclamation, long-distance highway construction and large dam foundation projects.

Q: How does the service life of these composite gaskets compare with ordinary fiber paper gaskets available on the spare parts market?
A: The reinforced composite structure improves creep resistance and medium corrosion resistance significantly. Under long-cycle heavy-duty working conditions, its service life reaches more than 3.43 times that of standard single-layer fiber paper gaskets.

Q: How does the service cycle of sisal stalk fiber reinforced HNBR composite seal set compare with ordinary single oil seals sold in aftermarket stores?
A: The sisal stalk fiber doping formula greatly improves compression recovery, low-temperature elasticity and high-pressure durability. Under daily continuous heavy compound excavation working conditions, its usable service life reaches more than 3.24 times that of standard single-piece oil seals.
