A vane seal that is custom-molded to a machined shaft and vane construct to create a one-piece shaft/vane/seal assembly gives the PRNA Series miniature rotary actuator its durability and strength, and increases its overall reliability. It is versatile enough for use in lubricated or non-lubricated filtered air at pressures ranging from 30 to 150 psi (0.2 to 1.0 MPa). A rounded vane design provides lower vane-seal bypass than typical rotary actuators. Standard internal bumpers provide quiet operation for high-speed applications. The stock rear output shaft is designed for easy accessibility and manual override in the event of an air pressure loss. The PRNA offers standard rotations of 90 deg., 180 deg. or 270 deg. Its operating temperature range is –5°C to 80°C (–23°F to 176°F), and its filtration requirement is 40-mm filtered, dry air.
