Buily-in field LCD display ( For Smart Positioner)
No resonance within 5-200Hz
Easy changeover between forward and ackward,and between single action and dual action
For small actuatoes,preventing vibration by making locator orifice smaller
Low air consumption,allowing the locator being economical
Splitting-range control within 1/2 without replacing parts
