• DX1-TD, TS (Duax)

Features

New Model

Duax is an epoch-making model that ball and ball seat are not rubbed at operation time. At the time of ball rotating, no touch and rub with ball seat, therefore there is not possibility to increase torque something bite between ball and seat. It is realized long life operation.

Animated Operation

● This model is realized long operation life for heavy abrasion conveyer line, powder, slurry
    line, high frequency line and so on.
● It is suitable for keeping pressure valve and relief valve of pressure conveying tank.
● Period of periodically shut down maintenance becomes long, and running cost can be
    reduced.
● It is not possibility to mix abrasived ball seat into fluid, food, food additives, medicine and
   so on.
