Features

The large-diameter NSCV for DN400–DN1200 is an axial-flow nozzle check valve with a streamlined disc and spring assembly coaxial with the flow path
The axial design provides the lowest headloss of any check valve type, important on long rising mains where energy savings are significant
The spring ensures rapid, slam-free closure on pump trip regardless of pipeline profile

Description

Heavy-duty non-slam for large transmission mains. The large-diameter NSCV for DN400–DN1200 is an axial-flow nozzle check valve with a streamlined disc and spring assembly coaxial with the flow path. The axial design provides the lowest headloss of any check valve type, important on long rising mains where energy savings are significant. The spring ensures rapid, slam-free closure on pump trip regardless of pipeline profile.
