Variable speed also gives the opportunity for a \u2018soft\u2019 start, reducing energy usage.<\/p>\n<span class=\"highlight highlight-blue\"><a href=\"https:\/\/engineernewsnetwork.com\/blog\/explosion-proof-variable-speed-valve-actuators\/\" target=\"_blank\" rel=\"noopener\">AUMA UK<\/a><\/span> worked closely with KOSO throughout the delivery phase of the project, helping to design a mounting that allowed the 5.5 inch drive shaft of the valve to interface accurately with the AUMA gearbox.<\/p>\n<p>Commenting, Joanne Handley, KOSO Kent Introl Project Engineer, said: \u201cThis is the largest butterfly valve we have ever supplied, and we have worked closely with AUMA throughout the project.
