SMS-TORK RA143DA Double Acting Pneumatic Actuator
High torque quarter turn, convertible to spring return.
A TORK RA143DA Pneumatic Actuator delivers high turning moment, designed to control ball, butterfly and plug valves in industrial valve automation. Moreover, its aluminium extrusion body gives superior corrosion resistance. In addition, the rack and pinion working principle provides precise flow control through 90° of rotation, therefore positioning is repeatable.
The double acting construction converts easily to a single acting model. Furthermore, compliance with ISO 5211 and NAMUR standards makes valve and directional valve mounting practical. As a result, ±5° stroke adjustment in both directions works alongside a leak-tight O-ring construction. Consequently, a position indicator makes line status easy to monitor.
TORK RA143DA Pneumatic Actuator — Technical Specifications
Ball and butterfly valves on industrial lines use this actuator as standard. In addition, chemical, food and treatment plants rely on it for flow control. Gas and liquid installations with automatic open-close duty fit it directly. Moreover, plug valves and rotary mechanism systems apply it widely.
Key Advantages
- High Torque Output: the rack and pinion design gives strong open-close torque.
- Easy Conversion: the double acting unit converts to single acting on request.
- ISO 5211 Compatibility: standard mounting bolts directly onto valves.
- NAMUR Interface: solenoids and switch boxes fit straight on for automation.
- Precise Stroke Adjustment: two way adjustment sets exact sealing positions.
Applications
- Ball and butterfly valves on industrial lines
- Flow control in chemical, food and treatment plants
- Gas and liquid installations with automatic open-close duty
- Plug valves and rotary mechanism systems
