To combat this, the lightweight aluminium body of each PremiAir is hard anodised both inside and out.
For extra durability and resistance to environmental corrosion, PremiAir actuators are also coated with an electrostatic powder coating.
If the application is hygienic or highly corrosive, such as caustic wash down areas or saline atmospheres, the PremiAir also can be specified with an optional special nickel protection finish both internally and externally.

Lined butterfly valves for corrosive applications
For demanding or corrosive processes in the chemical, pharmaceutical, cosmetic and food industries where common elastomers are unsuitable, Neotecha has developed the lined NeoSeal butterfly valve
Available in double acting or spring return models, the PremiAir compact body design is available in one standard size for both configurations.
Suitable for use with all quarter turn valves, the actuator can be fitted either with a bracket and detachable mounting plate or directly onto the valve, in accordance with ISO 5211.
This design feature combined with the industry perferred square/ star output drive allows direct interchageability with other actuator brands.
The double rack and pinion design delivers a reliable, linear torque output of between 27 - 2054 Nm for double acting configurations and between 15 - 1414 Nm for spring return models.
PremiAir features also include adjustable travel stops on all models, for precise travel setting in either direction.
Over-travel adjustment (at each end) is +/- 5 degrees and under-travel adjustment (at each end) +/- 10 degrees, with increased under-travel available on request.
Operating temperatures extend from -30C to +90C.
Tyco Valves and Controls manufactures a wide range of control accessories which are compatible with the modular design of PremiAir actuators.
A comprehensive selection of solenoid valves is available, with specifications including weatherproof rating IP65, explosionproof to E Ex m II T and E Ex ed IIC T5 and intrinsically safe to E Exia IIC T6.
For integration into - and control by - a network, the PremiAir can be connected to the AVID range of position monitoring equipment, which includes analogue and smart positioners.
The AVID range facilitates communication with AS Interface, DeviceNet, Fieldbus Foundation and Profibus network protocols.
PremiAir actuators are available from Tyco Valves and Controls, the leading name in manufacture and supply of valves, actuators and controls.
