How the Valve Operates

Designed specifically to heavy-duty applications, the sleeves are easily replaced in the field, prolonging valve working life. Sleeves provide 100% bubble tight seal and rely on the sleeves to seal. The sleeves are bi-directional and have an internal stiffening ring.

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.
