Valves take on high temperatures and pressures
Rated for temperatures to +650C and pressures to ASME 4500, the Raisteam gate valve from Raimondi is available for applications in the chemical, petrochemical, offshore and power industries.
Advanced aftermarket services for valve users
Tyco Valves and Controls now offers customers the benefit of guaranteed performance with an advanced aftermarket service, including dedicated valve repair for power plant installations.
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.
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 ISO5211.
This design feature combined with the industry preferred square/star output drive allows direct interchangeability with other actuator brands.
The double rack-and-pinion design delivers a reliable, linear torque output of between 27 and 2054Nm for double-acting configurations and between 15 and 1414Nm for spring-return models.
PremiAir's 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) is +/-10 degrees, with increased under-travel available on request.
Operating temperatures extend from -30 to +90C.
Tyco Valves and Controls manufactures a wide range of control accessories that are compatible with the modular design of PremiAir actuators.
A comprehensive selection of solenoid valves is available, with specifications including weatherproof rating IP65, explosion-proof 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.
