electrical-pneumatic I/P positioner
electrical-pneumatic positioner
Summary
1000 series electrical valve poistioner that is compatible with actuator, which receives 4~20mA DC current signal from controller or control system and will be transferred into air pressure to deliver to pneumatic actuator, then to control valve location.
Characteristics
1. Without resonance within 5~200Hz
2. Easy to change between direct action and reaction or single action and double action
3. For mini-type actuator that its vibration is prevented by reducing positioner
4. Air low consumption, economical
5. Don't change parts to realize split range control within 1/2 range.
Standard specification
