British Sugar Newark; Refined sugar section valve control upgrade project
Background
In 2018 we were asked to survey the valve positioners & switch boxes that were currently in use at British Sugar Newark factory sugar end of the production plant. This was carried out by our Director Jon Tayler, Siemens Valve Positioner Product Manager Ivor Jones (now retired) & Burkert Business Development Manager Emmet O’Sullivan. Along with the project team at the factory we developed a list of upgrades & essential replacements of both valve positioners & electronic switch boxes.
Challenge
At this time there wasn’t a standard for both the valve positioners & switchboxes on site, rather a legacy mix which had been delivered over a very long period, which was demonstrated by the eclectic mix of manufacturers products.
Solution
Along with the team we discussed the virtues of the Siemens SIPART PS2 intelligent electro-pneumatic valve positioners. The adaptability of the positioner to work with both rotary & linear valves, single or double acting, compact or remote mounting, the virtually zero air consumption unless it is moving position, the diagnostic values & ease of set up where all deciding factors in British Sugar’s decision to standardize on the SIPART PS2 as the positioner of choice for this project.
Correspondingly the Burkert switchbox, which combines the functionality of feedback switches, local open/ close indication & an integral solenoid valve. All electrical & pneumatic connections go to the switchbox with sufficient termination to allow for cabling through & using ‘in & out’ electrical connections if required. The compact IP65, die cast aluminium offshore paint specification enclosure with integral adjustable mounting bracket was chosen as the switchbox to standardise with for the project.
Result
We were also tasked with mounting, piping, & pre- commissioning all the Siemens SIPART PS2 positioners & Burkert 1061 switchboxes which has just been completed. PI provided all stainless-steel fittings, mountings & intermediate containment. We programmed all positioners to suit each individual actuator & in some cases, provided keys for the legacy actuators that did not meet current DIN standards.
Even though this had to be delayed 12 months due to the pandemic, the project was delivered in time & on budget which has resulted in the required standardisation & full familiarisation training for the engineering team at the factory.
