The primary swing check valve function is to allow forward flow of fluid in a pipeline while automatically preventing reverse flow (backflow). A disc swings open when flow is forward and closes when flow stops or reverses, protecting pumps, compressors, and upstream equipment.

The swing check valve function uses a hinged disc that swings away from the seat. This design creates a full, unobstructed flow path, resulting in lower pressure drop. Lift check valves, in contrast, require flow to lift a disc vertically against gravity, making them better for high-pressure applications but causing higher friction loss.

Yes. Thriveon offers customized trimming to meet exact pressure classes from Class 150 to Class 2500. We adjust the disc thickness, hinge pin strength, and body wall thickness according to your system's maximum allowable working pressure (MAWP).

For corrosive media like seawater or chemical slurries, we recommend CF8M (316 Stainless Steel) or Duplex 2205. These materials offer superior resistance to pitting and crevice corrosion. We also offer PTFE or PFA lining for the valve body and disc.

For standard sizes (2"-12") and materials (WCB/CF8), lead time is 15–25 days from order confirmation. For large orders (>100 units) or specialized alloys, lead time is 25–40 days. We ship via sea freight to Los Angeles or Houston in 18–25 days.

Absolutely. Our team of senior engineers (with 10+ years of experience) is available for free phone/email support for the entire lifespan of the valve. We can help with installation troubleshooting, sizing calculations, and maintenance schedules.
