Nozzle Check Valves

About this product

As a natural evolution to the non-return valve range, Advance Valve introduced their NZ-Series of axially operated Nozzle Check non-return zero leak valves with non-slam characteristics for special applications. The design incorporates the latest 3D designed tools and rigorous computational fluid dynamics analysis validated by experimental testing to ensure a well-matured, efficient, and reliable product range. Our NZ-Series of nozzle check valve design provide streamlined and unrestricted flow through the valve ensuring comparatively higher flow rates and low-pressure drop across these axial flow check valves which inherently ensures low energy loss in the line thus improving the operational efficiency of any plant in operation. The design takes advantage of the teardrop-shaped special venturi design to improve the static as well as the dynamic performance of the valve. Due to the robust design of NZ- series valves which encompass features like low failure rate, practically zero maintenance requirements, zero seat leakage and improved performance characteristics, these zero leak valves can be effectively, efficiently, and safely used in critical process applications in particularly large size gas and liquid flow pipelines.
