Valves join large-scale Profibus
installation
Burkert Fluid Control Systems has supplied Johnson Matthey with Profibus and AS-i compatible valves for one of the largest Profibus network systems in the UK.
Burkert Fluid Control Systems in conjunction with their partner distributor Fine Controls (UK) has supplied Johnson Matthey with Profibus and AS-i compatible valves for one of the largest Profibus network systems in the UK - part a major expansion at the company's precious metals refinery at Royston, Herts Johnson Matthey is one of the world's largest refiners of precious metals such as platinum, palladium, ruthenium and rhodium

The major expansion of the facilities at the Royston site required significant additions to their automated control systems.
The central control system located in the engineering office uses two Wonderware InTouch (Scada) servers and one InSEQL (data logging) server to communicate with local Omron PLCs across the site that run a number of Profibus networks.

Valves cut energy waste
Burkert's type 1066 valve control heads provide a decentralised method of opening and closing of process valves automatically, eliminating the need for the wasteful venting of control air.
System cuts costs of decentralised automation
The FreeLine system integrates fieldbus, I/O and pilot valves for use in the most demanding process environments.
An additional InTouch server and an InSEQL server are located in another building to give redundancy.
The Burkert valves, which are compatible with the latest Profibus and AS-i networks, are being used throughout the new control systems to supply feed liquors and reagents to many different processes.
Many of the chemicals used are strong acids and alkalis so the use of plastic valves is common.
The plant also uses many glass-lined steel reactors, which are heated and cooled at various stages of the process using Burkert Profibus steam valves.
The proportional valves connected to the Profibus PA network were supplied with software customised to Johnson Matthey's requirements.
The on/off valves, which use the latest AS-i 2.1technology, are connected to local AS-i networks that are then connected into Profibus DP networks.
Having already proved the performance and reliability of Burkert products in arduous duty applications on a smaller project, Johnson Matthey project engineer Paul Ashby says Burkert equipment was the obvious choice for both projects.
"These are new systems based on the very latest Profibus PA and AS-i 2.1 technology, so Burkert's technical support through Fine Controls and the product quality and reliability, proved invaluable", he says.
The Burkert components used on the projects were Profibus PA diaphragm and globe control valves and AS-i 2.1 globe, angle seat, polypropylene, stainless steel and lined diaphragm valves. Request a free brochure from Burkert Fluid Control Systems ...
