Briggs of Burton PLC
Bürkert was asked by hygienic process systems specialist Briggs of Burton to help deliver a large-scale manufacturing facility for life sciences company Purolite.
Creating a hygienic production facility that includes ATEX zone 1 areas is a complex task, especially when over 1400 control valves are needed.
Briggs of Burton was appointed as the main contractor to design and build additional production facilities consisting of 11 reactor vessels split across 9 production areas. Briggs was able to specify the manufacturer of the equipment being installed (except for the sensors) and chose Bürkert.
The size of the project meant that equipment would be located in various environments from outdoors to ATEX zone 1. Valves, sensors or control gear in potentially explosive atmospheres must be manufactured, certified and installed by qualified engineers.
Briggs needed suppliers that could deliver the valves, 3D CAD drawings and relevant certification to integrate into their overall 3D model. The drawings are essential for the design engineers to finalise the valve locations and ensure that all equipment will fit into the space available.
Briggs initially approached Bürkert for diaphragm valves but, during discussions, it became clear that Bürkert could deliver all the process valves needed, including butterfly, quarter turn, diaphragm and manual valves.
1400+ process valves were needed, each with certification documents and drawings. Bürkert set up an online resource for Briggs engineers to access all the information.
Logistics were simplified by Bürkert packaging together all the valves for each production area, labelled accordingly. This made installation quicker and ensured that valves were in the correct location.
Bürkert also created bespoke solutions for tank bottom valves and multi-seat valve blocks were manufactured to minimise the installation's footprint. Bürkert’s specialist manufacturing capabilities ensured that every part was delivered with the correct control gear and seals.
Damien Moran, Field Segment Manager Hygienic, Pharmaceutical for Bürkert, explains: “Our aim is to deliver the best solution for the customer and our products are designed so that they fit into local, decentralised or, as in this case, centralised control structures. With some additional advice, we were able keep the project costs to a minimum, while ensuring reliability.”
All automated valves have pilot solenoid valves in the control head, or in the case of the quarter turn valves, located in the switch box on top of the controller. This made a number of external valve islands and associated ATEX rated pneumatic control panels redundant, saving around £80,000.
“The whole process has been much simpler than we envisaged, and Bürkert's ability to make changes to individual valves quickly, plus their ability to manufacture bespoke valve manifolds has really helped in the delivery of this project.”

“The new production facility has worked out very well. The knowledge of the Bürkert engineers in hygienic process control has certainly paid off in the final design. The partnership between Briggs and Bürkert has delivered an efficient and cost-effective project.”
