美國topworx美國著名的閥門生產(chǎn)廠家，公司被艾默生收購后成為艾默生過程管理的一部分，擴充艾默生現(xiàn)有的閥門產(chǎn)品線，同時將艾默生PlantWeb數(shù)字工廠產(chǎn)品范圍延伸到開關(guān)閥及其它儀表。，Topworx閥門控制和定位感應(yīng)解決方案能使工廠、平臺和管道在苛刻的環(huán)境中實現(xiàn)更為智能化和有效的管理及控制。Valvetop離散閥門控制器與旋轉(zhuǎn)閥、線性閥以及執(zhí)行機構(gòu)配合使用，支持多種總線協(xié)議，并通過多項認證。go?switch限位開關(guān)可在各種環(huán)境條件下提供可靠性和耐用性，如極熱、極潮濕、極冷、易腐蝕和易爆環(huán)境。?
