Pneumatic Linear Valve Feedback Positioner
Pneumatic Linear Valve Feedback Positioner
Item Number: YT-1000L
Featuring a built-in LCD display for smart operation, it ensures no resonance within 5-200Hz, easy configuration, and low air consumption for economic performance.
YT-1000L Pneumatic Linear Valve Feedback Positioner is a device that receives DC current signal 4-20mA from the controller or the control system,and the precisely controls valveopening through pneumaticactuator.
Main Features and Characteristics
- Buily-in field LCD display ( For Smart Positioner)
- No resonance within 5-200Hz
- Easy changeover between forward and ackward,and between singleaction 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
