Pneumatic part-turn actuators are also suitable for use as actuators in protective and safety-related systems in accordance with EN 61508.
Our pneumatic part-turn actuators are dual-piston drives based on a rack and pinion design principle. This proven principle of operation guarantees the highest levels of reliability. Available versions include double-acting and single-acting part-turn actuators with integrated (fail-safe) spring return.
- Complies with requirements for use in safety- related systems to EN 61508
- Designed for use in zone 2 and zone 22
- Wide torque range
- Solid, corrosion-resistant housing made of aluminum
- Operates in any position
The honed surface of the cylinder bore ensures the pneumatically driven part-turn actuators achieve a long service life. Control pressures range between 2.5 bar and 8 bar. That achieves torques ranging from 5 Nm up to 10 000 Nm. The anodized aluminum housing and powder-coated cover ensure excellent corrosion protection, including in outdoor applications. The connections comply with DIN/ISO and Namur requirements. The part- turn actuators are also suitable for deployment in hazardous areas. Exposed to hazards from gases and vapours they are suitable for deployment in Zone 2, and Zone 22 areas when exposed to dust hazards. They are also suitable for use as actuators in protective and safety-related systems in accordance with EN 61508.
