Emerson-TopWorx is a leading producer of discrete valve controllers and GO Switches, which are fundamentally proximity sensors and limit switches combined. Based out of Louisville, Kentucky, TopWorx was acquired by Emerson in 2008 in order to expand their offering of valve instruments. MacroMotion became an authorized distributor of TopWorx discrete valve controllers and GO Switches in 2018. This partnership enabled us to more efficiently build custom cylinders suitable for aggressive industrial environments that feature precise control and monitoring of rod extension.
