Features

The NSCV for DN50–DN350 uses a spring-loaded disc that begins to close before flow reversal occurs
The spring force maintains the disc in near-closed position during the pump deceleration phase, so the disc is already seated or nearly so, when the reverse pressure differential arrives
This eliminates slam and the associated pressure transient
Available with stainless body for corrosive or high-purity service

Description

Spring-assisted non-slam for small to medium diameter. The NSCV for DN50–DN350 uses a spring-loaded disc that begins to close before flow reversal occurs. The spring force maintains the disc in near-closed position during the pump deceleration phase, so the disc is already seated or nearly so, when the reverse pressure differential arrives. This eliminates slam and the associated pressure transient. Available with stainless body for corrosive or high-purity service.
