Intelligent control solutions from a
single source
Tyco Valves and Controls has developed a comprehensive range of intelligent digital devices capable of providing control and monitoring in networked valve systems
Tyco Valves and Controls, a business unit of Tyco Engineered Products and Services, has developed a comprehensive range of intelligent digital devices capable of providing control and monitoring in networked valve systems A traditional hardwired arrangement of valves and field devices can no longer meet the needs of a demanding plant environment and the disadvantages of high costs for installation and downtime are reinforced by the fact that hardwired field devices are unable to provide detailed operational information

Digital networked systems are proving inherently more reliable, and deliver advanced functionality within the network.
With Tyco Network Solutions the customer has the added benefit of all devices manufactured and supplied from a single source.
Tyco digital network solutions require a single cable providing both power and communication, compared to the multi-core signal cables serving each piece of equipment in a hardwired system.

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
The digital network simplifies installation and substantially reduces the cost.
Tyco Network Solutions also function with standard, open network protocols such as AS-Interface, Profibus, Foundation Fieldbus, DeviceNet and HART, allowing the customer to more easily incorporate other equipment, including items from other manufacturers, into the control network.
The integrated fieldbus network enables the control room to command and receive detailed information from any network-connected device, including calibration data, maintenance dates, and performance information.
For example, a single AS-Interface system can support a network including up to 62 (Version 2.1) automated valves equipped with PlantNet monitors.
The protocol provides for up to 434 programmable discrete I/O ports on each network - 248 inputs and 186 outputs - and the specification includes superior diagnostics and a standard profile for analogue options.
The AS-Interface has a cycle time of less than 10mS (Version 2.1), and maximum cable length for the network is 100 metres from the PLC or master controller.
This distance can be increased using network repeaters.
Tyco Network Solutions have been successfully installed and implemented on a variety of plants across a wide range of industries, including, Oil and Gas, Petrochemical, Chemical, Food, Beverage, Brewing and Water.
The advent of FDT/DTM (Field Device Tool/Device Type Manager) technology, providing intelligent asset management and integration for fieldbus devices, makes implementation faster, easier and more efficient.
Tyco has recognised the benefits of this technology and is a member of the FDT-JIG (Joint Interest Group) with the vision of providing certified DTM status for all of its network and intelligent field devices, thereby ensuring a single engineering tool for open engineering and asset management.
