Introduction:
Electric pneumatic valve positionerYT-1000RIt is a method of receiving 4-20M DC current signals from a controller or control system,
A device that delivers air to the angular stroke pneumatic actuator to control the opening of the valve.
Characteristics of YT-1000R locator:
1. No resonance phenomenon within the range of 5-200Hz;
2. For positive and negative effects, there is a convenient transition between single and double effects;
3. For the vibration generated by small actuators, it can be solved by reducing the throttle hole of the locator;
4. Low air consumption and good economy,
5. It is possible to achieve split range control within 1/2 range without replacing parts.
