In harsh working conditions such as mine tailings transportation, chemical acid-base medium treatment and metallurgical slurry transportation, ordinary gate valves often fail quickly due to corrosion and wear. Frequent replacement not only increases operation and maintenance costs, but also causes production line downtime risks.
OUWEI corrosion and wear resistant gate valves have become the "key to pass" for extreme working conditions with three core technologies: first, the adoption of ultra-high molecular weight polyethylene lining + tungsten carbide alloy gate plate, which improves the wear resistance by 8 times compared with ordinary gate valves, and can operate continuously for more than 8000 hours without failure in slurry medium; second, the innovatively designed bidirectional pressure-bearing sealing structure can withstand 16MPa high-pressure impact and eliminate the hidden danger of medium leakage; third, the modular valve stem design allows maintenance without overall disassembly, greatly shortening maintenance time.
From the treatment of strong acid waste liquid with pH ≤ 2 to the transportation of slurry with solid content over 40%, OUWEI corrosion and wear resistant gate valves provide reliable protection for the stable production of high-loss industries with their "durable and robust" quality.
