Electric-Pneumatic Mechanical Positioner for proportional ball valve
Electric-Pneumatic Mechanical Positioner for proportional ball valve
Characteristics
| No resonance between 5 to 200Hz. |
| It is convenient conversion between direct and reverse acting, single and double acting. |
| For small actuator ca be reduce positioner orifice to prevent vibration. |
| Low air consumption. |
| 1/2 split range is available. |
