The KOSO EP800 series positions pneumatic actuator operated control valves by converting a 4-20 mA DC signal to air pressure, with valve stem position feedback for accurate positioning. Versions exist for single acting, double acting and KOSO 5200LA actuators.
Key features
- 4-20, 4-12 or 12-20 mA input (split range)
- Single acting (EPA800), double acting (EPC800), 5200LA (EPB800)
- Weatherproof, explosion-proof or intrinsically safe
- Standard, low temperature (-50 °C) and high temperature models
