NSW Pressure Sealed Bonnet Swing Check Valve – Class 900 to 2500, NPS 2"–24"

The NSW Pressure Sealed Bonnet Check Valve is engineered for high-pressure pipeline systems, offering robust non-return operation with reduced risk of water hammer. The pressure seal bonnet design ensures leak-tight performance in demanding services while minimizing maintenance in high-pressure environments. The valve body features precision casting in a wide range of corrosion-resistant materials, with optional full or reduced bore configurations.

Its swing-type disc allows smooth, rapid operation with low fluid resistance, and the sealing design supports both soft and metal options. Additional features like counterweight, damper, or gearbox can be included based on application demands. This valve type is well-suited for industries such as oil & gas, power generation, and chemical processing.
