Electrical actuator to control 0-90° valves with ISO-Top flange and a max torque of 20Nm. From 0-90° in only 4 sec. Suitable for power supplies of 24V AC/DC. Compact & strong housing (IP67) with visual position indicator. With manual override and two extra limit switches for position feedback.
The AG-020-B is a high-quality electric actuator to operate quarter turn valves such as ball valves and butterfly valves. The actuator can be mounted on valves with a ISO-5211 flange of type F03, F04 or F05. In just 4 seconds the actuator turns from 0 to 90°. The maximum torque is 20 Nm. The actuator has a robust, compact aluminum housing (powder coated) and is resistant to dust and moisture, provided that a properly sized cable is correctly installed. A position indicator at the top indicates the position of the actuator and is clearly visible from different directions. The device is equipped with a manual override.
The actuator is suitable for power supplies from 24 volts DC or AC (50/60Hz). With two switches the right setting (AC or DC) can be set. The nominal power consumption while running is 0.2 amps (peak current 1.2 A). The valve has 3-point control: besides the two contacts for power supply (plus and minus), there is one signal for opening (minus) and one signal for closing (minus).
The actuator can be used for ball valves and butterfly valves with 0-90° control. The valves can be made of different materials, such as brass, plastic or (stainless) steel. The actuator can be mounted on valves with ISO-5211 flange of size F03, F04 or F05. Some examples of commonly used applications are heating systems, irrigation, industrial automation, water supply and drainage, etc.
The required torque to rotate the valve should be well below the maximum torque of the actuator (20 Nm). Please note that the breakaway torque of a ball valve is about 30% higher than the torque while running. The medium, the temperature, the pressure, and the period of inactivity have an influence on the required torque. Always follow the specifications of the manufacturer of the valve.
