Overview

Designed to DIN dimensional standards, this lift check valve guides a disc vertically against its seat to deliver tight, automatic non-return performance. Forward flow raises the disc off the seat; when flow stops or reverses, the disc settles straight back down to close the line. The guided action gives quick, positive shut-off and makes it well suited to horizontal pump discharge and metric-piped systems where DIN-compatible face-to-face and connections are required.
