Description:
DURAVIS Single Acting Rotary Pneumatic Actuators are to perform on/off and proportional control of butterfly valves, ball valves, plug valves and dampers. DURAVIS PAR Series' compact rack and pinion construction means that actuators are lightweight and occupy a minimum of space, allowing users to install them in any orientation between close pipe configurations. The necessary supplied air must be between 4 to 8 bar for a proper operation.
DURAVIS PAR-... X090SR Series are 90 degree rotation (quarter turn actuators) and operate according to single acting / spring return principle. Why do we use a single-acting pneumatic actuator? These actuators which have modular construction are generally used in the applications require the safety of opening or closing in the event of system failure.
