The Electro-Pneumatic positionalYT1000-R is used for operation of pneumatic rotary valve actuators by means of electrical controller or control systems with an analog output signal of DC4 to 20 mA or split ranges and Dome Indicator is attached.
1. The confirmation of positioner`s operating angle is possible by watching in the long distance due to Dome Indicator.
2. The change of RA/DA Action is convenient; it is able to apply to single or double acting actuator.
3. It is possible to prevent the hunting with orifice to the small actuator.
4. It is economical due to less air consumption.
5. It is able to control the (1/2) split range with simple operation without replacement of parts.
