Product catalog summary

Pneumatic Actuators Overview

Features:
The OMAL aluminium two-stage "DD" pneumatic actuators are designed for precise control with a metering rotation angle of up to 45° and a maximum rotation angle of 90°. The breakaway torque is specified in Nm at 5.6 bar air supply.

Working Conditions:
These actuators operate within a temperature range of 0°C to +80°C, or -20°C to +80°C with dry air. The air supply should be between 5.6 bar and a maximum of 8.4 bar, using compressed filtered air, which may be lubricated with non-detergent or NBR compatible oil.

Codes, Dimensions, and Materials:
The document provides a dimensional table for various actuator models (e.g., DD030401S, DD060401S) with specifications for size, dimensions (A, B, C, D in mm), and weight in kg. Materials used include aluminium alloy, stainless steel, steel alloy, acetalic resin, polyurethan, nitrilic rubber, PTFE, and Viton.

Operating Diagram and Use:
The actuators are used for filling and metering fluids or solids-mix materials. They feature a double-acting actuator with additional cylinders for stroke adjustment, controlled by solenoid valves (E1 = 5/2; E2 = 3/2). The system allows for precise control of valve positions, enabling both rough and fine metering.

Conclusion:
The OMAL device is suitable for applications requiring consistent quantities over long working cycles, with the ability to adjust metering from 0° to 45°.

Operating diagram General use and working condition USE: Filling and metering of fluids or solids-mix materials by means of a special metering device. Double acting actuator for fine or rough metering. EXECUTION: With UNI EN ISO 5211. WORKING SYSTEM: The basic model consists of an Omal double acting actuator, equipped with two additional cylinders whose inner-pistons, by means of a stroke adjustment device, stop the rotating angle of the actuator to a pre-set position, preventing it from a complete rotation and influencing the total valve flow pressure. This device is driven by two solenoid valves....
