One Multi-lobe Cam
The cam provides field-changeable linear, split-range linear and equal percentage control characteristics. Custom characteristics are available on special order.
Adjustment of the positioner zero can easily be accomplished by means of the adjustable spring button. Further zeroing can be performed through the turnbuckle assembly on linear motion actuators.
Premium performance is the standard on the models 4700P/4700E and 4800P/4800E positioners. Internal components are manufactured of corrosion-resistant materials for protection against the harshest environments.
All adjustments are fully enclosed for protection from the environment.
Positioner action can be reversed without additional parts (4700P/4800P only). The same mounting orientation is used for both direct and reverse action.
