Burkert Globe Valves with Integrated Positioners Provide Ideal Package for Control of Water Features
Burkert globe valves equipped with Top Control positioners are providing precise control of water height on a prestigious new water feature currently being commissioned in the centre of Copenhagen.
Supplied by a Burkert premier partner, Fine Controls, the valves control 40 individual vertical water jets, each valve receiving a position signal from a central PLC to control the height of the water jets in time to music.
"The system that we have supplied, based upon Burkert globe valves with integrated Type 8630 positioners, is far more cost effective than one based upon pump control," said Gareth Hall of Fine Controls. "In addition, the Burkert solution consumes less space, and with 24Vdc actuation, is far more energy efficient."
A highly regarded systems designer and builder, Fine Controls specified and sized the integrated Burkert valve units, and then supplied samples for tests, which proved entirely successful. "This was all in day's work for us," commented Gareth Hall. "With our extensive product range we are regularly requested to provide advice on how best to integrate specific products into small and medium sized systems. Many of our customers are happy to let us take it further, involving us in designing, building and commissioning bespoke systems for use across all industry sectors."
Fine Controls has also recently supplied the same Burkert solution for two other fountain projects, in Luton Town Centre and the Victoria & Albert Museum. The high quality water feature at the V&A is within the external garden courtyard of the museum in South Kensington. The feature has an unusual elliptical form, and has a number of operational modes that can be selected by the client dependent upon the usage of the space.
The TopControl 8630 combined with Burket globe valves provides the ideal combination across all of these projects, not least because of its reliability, precision and ability to interface easily with PLC systems and Profibus networks.
The Type 8630 is an electro-pneumatic positioner designed for use with pneumatically actuated control valves - piston, globe, ball or butterfly types. With its numerous software functions, the TopControl Type 8630 may be used as a process controller with PID characteristics, a servo controller for process valves, or as a straightforward pneumatic positioner, with either single or double acting actuators.
