PNEUMATIC ACTUATORS
Double Acting Pneumatic Actuator
tagline
Product Overview
DA-series double acting pneumatic actuators use air pressure for both opening and closing strokes, delivering balanced torque in both directions with no spring resistance. The result is higher effective torque per size and smoother control — ideal for modulating service, frequent cycling and applications where fail-safe positioning is not required.
Key Features
- Balanced torque in both directions
- Higher effective torque per frame size
- Smooth modulating / proportional control
- Fast cycling capability
- ISO 5211 & NAMUR compliant
- Low air consumption
- Positioner-ready (VDI/VDE 3845)
Applications
ISO 5211 / NAMUR
±1° repeatability
Positioner-ready
OEM / ODM

FAQ
Questions Buyers Ask
When should I choose double acting instead of spring return?
Choose double acting when fail-safe positioning is not required — you get higher torque per size, smoother control and lower cost. For safety-critical lines, spring return or a double acting actuator with an external air reservoir is recommended.
Can double acting actuators be used for modulating control?
Yes. With a positioner and feedback, DA-series actuators provide precise proportional control for throttling applications.
What accessories do you recommend?
Limit switches, solenoid valves, positioners, air filter regulators and manual overrides are all available. We can supply a complete pre-assembled package.
