Product catalog summary
Specifications:
The pneumatic actuator is designed according to DIN/ISO 5211 and DIN 3337 standards. It features a metering rotation angle of up to 45° and a maximum actuator rotation angle of 90°. The torque values are specified in the actuator tables, with the code numbers following 'DD' indicating the breakaway torque in Nm at 5.6 bar air supply. The operating temperature ranges from 0°C to +80°C, or from -20°C to +80°C with dry air. The nominal air supply pressure is 5.6 bar, with a maximum of 8.4 bar. The actuator uses compressed, filtered air, which does not need to be lubricated, but if lubrication is used, it should be with non-detergent or NBR-compatible oil.
Technical Features:
The actuator dimensions and weights are provided in a table, with sizes ranging from DA 30 to DA 480, and corresponding weights from 1.8 kg to 14.3 kg.
General Use and Working Conditions:
The actuator is used for filling and metering liquids or semi-solids using a special metering device. It is a double-acting actuator suitable for both fine and rough metering. The system includes an Omal double-acting actuator with two additional cylinders that adjust the stroke to control the rotation angle, thus influencing the valve flow. The device is operated by two solenoid valves (E1 = 5/2; E2 = 3/2), where E1 controls the actuator and E2 controls the external cylinders.
Working System:
Examples of operation include: with a completely closed valve (0°), E1 supplies air to A and exhausts B, while E2 exhausts B1. With a completely open valve (90°) for rough metering, E1 exhausts A and supplies air to B, while E2 exhausts B1. Upon reaching the desired fill level, the rough signal is turned off, and air flows through E2, adjusting E1 to move the external pistons to the desired angle (e.g., 30° for fine metering), reducing the valve flow. The desired metering can be adjusted from 0° to 45° using control 'D'.
Conclusion:
The OMAL device is suitable for applications requiring consistent quantities over long working cycles.
