Application of wear-resistant hard seal ball valve
Typical application scenarios
Why choose wear-resistant hard seals for industry working conditions
Coal chemical lock slag valve, black water valve, 4-6.5MPa hard particle slurry with anti scouring, anti jamming, and anti cavitation properties
Petroleum refining and catalytic cracking 550 ℃ regenerated flue gas, hydrogenation 42MPa high-pressure hydrogen gas resistant to high temperature and high pressure, and resistant to catalyst particle erosion
450 ℃/16MPa main steam and supercritical boilers in power and thermal power plants are resistant to high temperatures, have zero leakage, and are fire-resistant
The wear-resistant life of mining iron concentrate, tailings, and coal water slurry transportation is 3-5 times that of ordinary valves
Metallurgical 1200 ℃ hot blast furnace combustion supporting air, blast furnace slag slurry resistant to extreme high temperatures, and resistant to particle impact
Polycrystalline silicon/photovoltaic silicon powder slurry, high hardness particle diamond coating has a lifespan 2-3 times that of tungsten carbide
Advantage
✅ High temperature and high pressure resistance (-196~600 ℃+) ⚠️ Under low pressure conditions, there is a high friction force on the metal surface, which may cause slight leakage (which can be improved by increasing the sealing grease)
✅ Wear resistant, long service life (fully welded up to 30 years) ⚠️ The processing accuracy requirements are extremely high, and the cost is higher than that of soft seals
✅ Zero leakage, ANSI Class V ⚠️ Improper opening and closing operation can easily scratch the sealing surface
✅ Suitable for media containing particles/corrosive substances ⚠️ The operating torque is slightly larger than that of soft seals (but can be reduced by 40% after optimization)
✅ 90 ° quick opening and closing, low fluid resistance
