Double Acting Actuators for Heavy-Duty Valves
Bidirectional force capability for extreme industrial applications
1Symmetrical Torque and Power
Consistent Bidirectional Force: Air pressure on both piston sides generates equal torque for opening/closing (e.g. 1,500Nm for DN600 gate valves at 100 bar).
2Durable Construction
Reinforced Components: Withstand 50,000+ cycles/year in mining slurry systems.
3High-Speed Performance
Spring-Free Design: Achieves 1-2 second 90° rotation for emergency shutdowns.
4Pressure Flexibility
| Pressure Setting | Typical Application |
|---|---|
| 6 bar | Butterfly valve modulation |
| 10 bar | Sluice valve closure |
5Low Maintenance
Field-Replaceable Parts: Simplified design with accessible seals/bearings for offshore use.
6Non-Fail-Safe Safety
Pure Pneumatic Control: Eliminates spring mechanics in non-critical processes like cement production.
Steel Mill Application
Stainless steel actuators with silicone seals reliably operate 500°C oxygen valves, preventing furnace damage during thermal cycling.
Double acting actuators deliver unmatched reliability for oil & gas, mining and power generation applications through consistent bidirectional force and extreme environment durability.
