APNRDA API Pneumatic s.r.l. Speed regulator

Speed controllers for double acting (APNRDA type) and spring return (APNRSR type) pneumatic actuators, to mount directly on the actuator or using with NAMUR solenoid valves and/or positioners. These speed regulators was designed with an advanced throttling technology that was specifically made for the use of controlling the opening and closing speeds of pneumatic actuators. The speed controller is able to control the rotary speed of the actuator at any rate accurately, consistently and safely without the fluctuation that is commonly found in the standard speed controllers.
