Product Overview

The Özkan Tilting Check Valve No. 9883 is a tilting type check valve featuring a lever and counterweight. It is a resilient seated valve with a short overall length, small volume, and low weight. It is suitable for a wide range of nominal diameters, from DN 150 to DN 1400. The valve's design allows it to be installed in both vertical or horizontal pipelines, and its variable counterweight allows for adaptation to individual operating conditions.
