Pneumatic valve positoner
Summary
Pneumatic valve positioner YT-1200 that receives 3~15psi pressure signal from pneumatic controller or control system, and through operating pneumatic actuator to control valve location device.
Characteristics
1. Fine small structure
2. Forward and reverse, single action and double action that they can be easily changed.
3. For single pneumatic actuator, Narrowing the positioner's throttle orifice is used for avoiding vibration
4. Low air consumption, economy
5. Don't change parts, split range control within 1/2 will be realized via easy operation.
