World Pumps - KSB launches pneumatic quarter-turn actuators

The KSB Group has introduced a new generation of pneumatic 90° quarter-turn actuators.

The double- and single-acting pneumatic Actair Evo and Dynactair Evo actuators are designed for actuating all types of part-turn valves, such as butterfly valves, ball valves and plug valves. Steam Check Valve

Applications include water treatment, wastewater treatment, power generation, general industry, refinery engineering and shipbuilding.

The double-piston KSB actuators can be operated with compressed air to ISO 8573-1 from 3 to 8 bar. The maximum torque is 8000 Nm for the double-acting type series and 4000 Nm for the single-acting variant. The maximum ambient temperatures should be between -50°C and +150°C. With their IP68 enclosure, the actuators are suitable for use in a maritime environment. This means that – in the event of flooding – they will remain water-tight for about 169 hours at a depth of up to 30 metres.

The pneumatic connections comply with NAMUR requirements.

As standard, the actuator is fitted with a position indicator and adjustable mechanical stops. The actuators are lubricated with silicone-free grease at the factory, their gear housings are made of anodised aluminium alloy. With their standardised interfaces, the actuators can be connected to higher-level process control systems with solenoid valves, positioners and diverse digital and analogue control units.
