Kaike Cracking Valves
Shanghai Kaike specializes in high-end petrochemical cracking valves, integrating R&D, intelligent manufacturing, and full-lifecycle maintenance to achieve domestic substitution for imported alternatives. The products have been deployed in over 100 major petrochemical projects across China.
Key Technical Features:
-
Three-Stage Anti-Coking Sealing System – A patented design that prevents coke buildup and ensures reliable sealing during high-temperature cyclic operations, eliminating sticking and external leakage.
-
Special Hard-Alloy Surfacing Welding – Applied to critical sealing surfaces, delivering exceptional erosion and abrasion resistance, with performance 90% superior to conventional imported products.
-
High-Temperature Endurance – Withstands cracking gas temperatures exceeding 800°C, maintaining structural integrity and sealing under severe thermal cycling.
-
Topology-Optimized Valve Body – Advanced lightweight casting design reduces overall weight while preserving strength, minimizing thermal stress and extending service life.
Performance Advantages:
-
ANSI Class VI Sealing – Achieves near-zero leakage, the highest industry standard for tight shut-off.
-
Superior Durability – Long-term operation without sticking or jamming, significantly outperforming German and American counterparts in lifespan.
-
Full-Size Range (DN300–DN1500) – Customizable to diverse process requirements with consistent quality and reliability.
Maintenance Support:
Provides full disassembly, seal replacement, seat surfacing repair, and actuator calibration. For aging imported valves, localized parts replacement and structural upgrades are available, backed by 24/7 emergency response and substantial on-site spare parts inventory.
Backed by over a dozen patents and validated in a CNAS-accredited lab, Kaike cracking valves deliver proven performance, offering a dependable, cost-effective alternative to imported products
