Check Valve
Swing-type & Lift type check valves come with metal seats. These valves are installed in pumping applications to prevent back flow and can be used for both drinking water and wastewater. The disc is connected to the shaft via a flexible bush, which allows the disc and valve seat to adjust exactly. These valves are available with either closed bushings or protruding shaft ends, where a lever with a weight or spring can be fitted to mitigate pressure surges. They can be installed in horizontal or vertical upward flow piping.
- Fine-grained metal seats.
- Uni-directional valve with tight shut of f sealing capability.
- The valve size is available in DN25 to DN400, with flanged ends, and has #150, #300, #600 and #800 pressure ratings.
- Adaptability to fit between companion flanges of all popular flange standards.
