2009年3月16日-艾默生過程管理推出了Fisher 8580旋轉閥，提供堅固的可靠性和高循環(huán)壽命，提高工廠的可用性。 大量的實驗室對Fisher 8580進行證實以確?？煽啃浴ＡW試驗，以確定循環(huán)壽命、疲勞壽命、振動性、溫度限制和壓力的限制。此外，試驗對Fisher 8580閥體進行了關于原料、磁盤、密封件、軸和軸承確保阻力的條件可能導致惡化的性能。 新的旋轉閥可以很容易地安裝在水平或垂直方向不損害性能或循環(huán)壽命。這也使得左邊或右邊的安裝閥門致動器，可進出任何安裝。 Fisher 8580的磁盤設計賦予它一個大約線性流量特性提供精確的調節(jié)控制。閥門是提供帶有軟或金屬密封，提供能力增強停止。密封的互換能力最大限度地減少零件庫存的要求。 為了方便使用在世界所有地區(qū)，符合API的Fisher 8580 美國機械工程師協(xié)會和EN標準。開會的閥體的PN 10通過的PN 40 ， CL150和CL300評級。面授和提高面對面層面滿足EN 593 、API 609 、和MSS-SP68標準。 關于艾默生過程管理 作為艾默生集團的業(yè)務之一，艾默生過程管理為工業(yè)生產(chǎn)、加工、分銷提供自動化服務，應用在電力、供水和水處理、化工、石油天然氣、精煉、紙漿和造紙、能源、食品飲料、生命科學以及其他領域。艾默生將先進的產(chǎn)品和技術結合在為不同工業(yè)而設計的工程、咨詢、項目管理和維護服務中扮演著關鍵的角色。艾默生過程管理旗下的品牌有：PlantWeb, Micro Motion, Fisher, Rosemount, Mobrey, Daniel, Bristol, DeltaV, Ovation, 以及 AMS Suite。 [font=times]original text [/font] [font=times]Emerson releases Fisher 8580 rotary valve[/font] [font=times][color=#708090]March 16, 2009 - Emerson Process Management released the Fisher 8580 rotary valve that delivers rugged reliability and high cycle life, increasing plant availability. Extensive laboratory verification was performed on the Fisher 8580 to ensure reliability. Mechanical tests were conducted to determine cycle life, fatigue life, vibration resistance, temperature limits, and pressure limits. In addition, tests were performed on materials for the Fisher 8580 valve body, disk, seals, shaft, and bearings to assure resistance to conditions that could lead to deterioration in performance. The new rotary valve can easily be installed in either a horizontal or vertical orientation with no detriment to performance or cycle life. This also enables left- or right-hand mounting of the valve actuator, allowing access for any installation. The Fisher 8580’s disk design gives it an approximately linear flow characteristic to provide precise throttling control. The valve is offered with either a soft or metal seal, providing capability for enhanced shutoff. The interchangeable seal capability minimizes parts inventory requirements. To facilitate use in all world areas, the Fisher 8580 meets API, ASME, and EN standards. The valve body meets PN 10 through PN 40, CL150, and CL300 ratings. Face-to-face and raised-face dimensions meet EN 593, API 609, and MSS-SP68 standards.
