Valtek GS調(diào)節(jié)閥
Valtek GS是 款用于控制連續(xù)加工中非臨界流體回路的閥門-執(zhí)行器-儀表全集成產(chǎn)品。Valtek GS設計打破常規(guī)，用 低的成本實現(xiàn)了 好的產(chǎn)品性能。遵循簡約設計理念，找尋各種可能性， 終用集成產(chǎn)品控制的寬度和深度為Valtek 正名。
VNAF Trunnball DL是福斯工程師結(jié)合80多年球形控制閥制造經(jīng)驗全新開發(fā)的耳軸固定球閥。球由2個大型低阻力的耳軸承支持，即使在 大壓差時依然保持低扭矩。擁有雙向密封、低阻力和高可控性等特點，本產(chǎn)品特別適合隔離，開/關和調(diào)節(jié)控制應用。NAF Trunnball DL的材質(zhì)為不銹鋼或碳鋼，也有其他可選，如鈦等等。
NAF Trunnball DL性能優(yōu)良故障少的原因：
? 彈簧式閥桿密封可使自動開/關和控制功能壽命長、免維護、操作安全。
? NAF Turnex可直接安裝，性能好、防振、設計緊湊。
? 防井噴閥桿提供高轉(zhuǎn)矩傳遞、反沖小，超控性能優(yōu)良
? 耳軸固定球閥為雙向密封式。
? 低阻力軸承實現(xiàn)低扭矩和平穩(wěn)操作。
? 獨 無二的Z型切割選項可以使氣蝕和噪聲 小化，操控更完善。
? 規(guī)格多，DN 150–800，從 6” 到 32”
? 服務便捷設計，閥體結(jié)合面采用偏心設計，可以輕易更換球和密封，同時不影響閥桿和執(zhí)行器。
? 金屬閥座可以選擇合金6或者PTFE涂層。
NAF Trunnball DL的設計特別適合加工工業(yè)苛刻的工況條件，其介質(zhì)復雜和壓力條件對閥門設計、材質(zhì)和性能都有較高要求。
The NAF Trunnball DL is a full-bore trunnion-mounted ball valve, developed by Flowserve engineers with more than 80 years of experience manufacturing ball valves. The ball is supported by two large, low friction trunnion bearings for consistent low torque, even at high differential pressures. Due to its bidirectional tightness, low friction and high controllability, it is an excellent choice for isolation, on/off and modulating control applications. NAF Trunnball DL is supplied in stainless steel or carbon steel as a standard, but is also available in other materials, such as Duplex, titanium, and others.
The NAF Trunnball DL has the following features that optimize performance and reduce plant downtime:
•Spring loaded stem seal packing that provides long, maintenance-free and safe operation in automated on/off and control service safe operation in automated on/off and control service
•Direct actuator mounting capabilities of the NAF Turnex actuator for a high performance, vibration resistant, compact valve package
•Sturdy, blowout-proof stem providing high torque transmission with minimum mechanical backlash for optimum controllability
•Trunnion-mounted ball providing bidirectional tightness
•Low friction bearings for low torque and smooth operation
•Unique Z-trim option that minimizes cavitation and noise and has excellent control characteristics
•Extensive size range, DN 150–800, size 6” to 32”
•Easy-to-service design, due to the off-center joint face of the valve body, allowing for easy replacement of the ball and seals without the need to remove the stem and actuator
•me-tal seats with a rigid welded overlay of Alloy 6 or alternatively, me-tal supported, reinforced PTFE seats
The design characteristics of NAF Trunnball DL are particularly suited to the most challenging operating conditions in the process industry, where difficult media and demanding pressure conditions make severe demands on the design, materials and performance of the valve.
