How the liner works

The liner seat is flush with the bottom of the port eliminating debris and slurry, allowing a leak-free seal when closed. The liner also extends over the flange face essentially creating a gasket type seal when installed in the line, thus eliminating additional gaskets.

Applications

The valve is suited for mining and mineral processing, power generation, sand/gravel, chemical & soda ash, pulp & paper, environmental & effluent, dry feeds & powders.

Actuators

All types of actuators can be fitted; electric, gearbox, hydraulic, pneumatic and handwheel.
