In any other application the control task could be easily performed by a standard, 3-way solenoid valve but in this case the whole process, and hence the valves, needs to be maintained at 180\u00b0C.<\/p>\n<p>Although the Protea designers had a solenoid control valve that could be used within this design, some questions had been raised in the past about the long term reliability of the valve.<\/p>\n<p>In order to deliver an improved product to the end user, a search was launched for a better component.<\/p>\n<p><strong>High temperature solutions<\/strong><\/p>\n<p>Chris Muten, Design Engineer at Protea, takes up the story: \u201cThe real challenge for this control valve is the high operating temperature, not just of the medium but the surrounding environment as well. It is essential that the coil, electrical connections and process connections can all withstand at least 180\u00b0C.<\/p>\n<p>\u201cHaving already used B\u00fcrkert solenoid control valves in other applications, we were aware of the high build quality and long term reliability of their products. This led us to enquire about their high temperature range of solenoid valves to see if there was a product that would fit our design.<\/p>\n<p>\u201cA conversation with Clive Halliday, North West Account Manager for <span class=\"highlight highlight-blue\"><a href=\"https:\/\/engineernewsnetwork.com\/blog\/burkert-pneumatic-control-valve-island-interfaces-directly-with-siemens-et-200sp\/\" target=\"_blank\" rel=\"noopener\">B\u00fcrkert<\/a><\/span>, soon led us to a variant of the Type 355, 3-way solenoid valve, constructed in stainless steel and incorporating PTFE seals. This high temperature variant would prove to be the solution we were looking for.\u201d<\/p>\n<p><strong>Adapting to new applications<\/strong><\/p>\n<p>Having agreed on the specification of the solenoid valve, the Protea engineers designed a mounting block that would allow four solenoid valves to be positioned together and also help to maintain the temperature within the analysis pipework at 180\u00b0C.<\/p>\n<p>Clive Halliday explains: \u201cThe speed with which this project has been delivered can be largely attributed to the huge diversity of the Burkert product range. Coupled with the extensive knowledge of our application engineers, we make every effort to deliver the most effective and reliable solution available.\u201d<\/p>\n<p>Chris Muten concludes: \u201cThe work to create the prototype of this analysis system has certainly paid off because we have since received two further orders for very similar equipment, albeit for entirely different applications. The analysis and monitoring of exhaust systems is very important for companies to ensure they comply with regulatory standards and so it is essential that the equipment is both accurate and reliable.<\/p>\n<p>\u201cThe fact that <span class=\"highlight highlight-blue\"><a href=\"https:\/\/engineernewsnetwork.com\/blog\/precision-flow-control-for-efficient-accurate-pneumatic-conveying-systems\/\" target=\"_blank\" rel=\"noopener\">B\u00fcrkert<\/a><\/span> will guarantee the performance of their solenoid valve up to 250\u00b0C is very important to the reliability of our equipment.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The control of emissions from combustion engines has made several headlines in the past, bringing the subject to the fore on several occasions.
