1) 3 position control using only 4 wires plus air supply (for more than 3 positions - contact
           Kinetrol)
2) Mid position setpoint anywhere in angular range
3) Direct mounting onto standard Kinetrol 1/4 turn actuators - Double acting or spring 
           return on some models
4) Easy adjustment of setpoint by choice of methods selected by links - On-board 
           potentiometer, external potentiometer or 4–20 mA signal
5) Precise electronic circuit in robust metal enclosure (sealed to IP65 / NEMA 4)
6) Includes direct mounted standard solenoid valves outside positioner box for 
            robustness and accessibility

Options
* Limit switches (two mechanical or proximity sensors) inside same box
* 4–20 mA mid position angle feedback circuit inside same box
* 240 V ac, 115 V ac, 48 V dc and 24 V dc supply options

Consult Kinetrol for these options
* Spring return from mid position on electrical failure (fail action functions without air pressure)
* 'Hold' position on electrical (holds without need for air supply pressure)
* Double acting 'fail down' on electrical failure (requires air supply pressure)
