asco公司成立于1888年，是一家電梯、壓縮機和發電機控制的制造商。1910年，該公司發明了一種新型的電動控制裝置，即電磁閥。該公司的創新傳統導致了一系列產品的廣泛應用，從兩個位置/關閉閥到整個流量控制系統，設計為提供數以千計的客戶解決方案。
在上世紀70年代引入了額外的產品，如空氣操作閥、手動復位閥、壓力和溫度開關，以滿足不斷增加的新客戶應用需求。1982年，隨著收購了一家微型微型電磁閥制造商Angar科學公司，該公司再次擴大了產品線。
1985年，asco被世界上zui大、zui受尊敬的工業公司之一的艾默生收購。在這十年的后期，愛默生購買了歐洲的氣動閥門供應商Joucomatic，并將其添加到科科的家庭。
2008年，艾默生將其在北美地區的業務和數字技術公司合并，組建了一個統一的業務，為廣泛的行業應用提供全面的流控制和氣動解決方案。Numatics是氣動和運動控制產品的制造商。公司成立于1945年，有著豐富的創新理念和技術突破的歷史。由于在1952年引進了十億循環、疊圈和套筒式閥門，Numatics建立了其設計的聲譽。隨著2005系列和2012系列閥門的發展，隨著*集成現場總線電子技術的發展，新的行業基準的價值、可靠性和性能再次得到了提高。
2016年，asco和Numatics業務在該公司的品牌下統一，為該公司下一階段的增長奠定了基礎。
