美國福斯 Valtek GS 調節閥

美國FLOWSERVE福斯詳細說明

Valtek GS將新設計的GS線型球形閥、新Valtek Logix® 420帶自動校正功能的數字定位器、FlowAct氣動隔膜執行器組合在 起。這種集成設計大大降低了購置、安裝、操作和維護的成本。同時具備優越性能：

即使達到常規球形閥 大流量，也可以保持優異的浮動范圍和重復性。

卓越的控制精度

無需套管直接安裝的數字定位器

不同的切割和材料選擇滿足幾乎所有應用條件

無需工具和工藝流程經驗的維修員即可實現快速安裝和簡單設置

常備，獲取方便

這款新產品不僅滿足了加工企業對性價比的要求，也保證了產品 貫的高品質。

產品規格：
DIN: DN 15 - 150 / PN 16 - 40
AMSE: 0.5” to 6"; 壓力 別：150 和 300
主體材質：不銹鋼

標準現場負載系統：TA-Luft/ISO 15848-1， 高溫度可達400° C

溫度范圍：-60°C ~ 400°C(-76°F ~ 752°F)
連接方式：法蘭
漏損等 ：標準為IV ；IV 和VI 可選
可選項：膜盒密封、伸長型上閥蓋、低噪音和防氣蝕切割

執行：氣動隔膜和電動線性執行器

特點：
大容量流量：Valtek GS可以替代大部分流程控制產品，應用于大流量的常規應用中，如石油天然氣、化工、電力等等。與同款產品相比，Valtek GS的 大容量流量提升了25%。

氣蝕調節/噪聲衰減：Valtek GS特別適合要求高Cv，噪聲控制和氣蝕調節的常規應用。這些切割解決方案包括非平衡、壓力平衡和多流抗噪、防止氣蝕。

更小、更輕、性價比更高：相同 大容量流量產品，Valtek GS體型更小，質量更輕，性價比也更高。

大尺寸塞桿：幾乎消除了軸出故障的可能。重載塞桿有較大的表面區域來減少氣門導管磨損，從而提高可靠性，延長閥門壽命。如需緊急關停，堅固的塞桿可以承受執行器的推力，并推至閥門的單座切割。

更深的填料盒：除標準TA-Luft，現場裝載排放控制填料方式外，支持大部分的填料配置。填料包括上方設備和滑片設備。后者是用來去除塞桿上的液體的。上方設備和滑片設備的距離足夠遠，以防污染介質。

雙重導管：確保精確塞住、閥座對齊。稀疏排列、石墨畫線的不銹鋼導管使可用溫度范圍更大，避免導管/塞桿磨損

柱塞形閥芯設計：可適用于修改后的等百分比、線性和快速開啟流動特性。以及多種切割類型、優異的變化幅度、重復性和清晰度。

 

 

Based upon the proven Valtek design philosophy, the Valtek GS integrated control valve packaging consists of the newly designed GS linear globe valve, the new Valtek Logix^® 420 digital positioner with automatic calibration, and the FlowAct pneumatic diaphragm actuator. Its integrated design makes it a low total cost value to buy, install, operate and main­tain. Yet, it delivers best-in-class performance with:

• Excellent rangeability and repeatability for the highest flow rates in a globe type general service valve

• Excellent control accuracy

• Direct mounted digital positioner without tubing

• Trim and materials options to handle virtually all general service requirements

• Quick installation and simple setup by maintenance technicians without the need for instrument or pro­cess engineering skills

• Off-the-shelf availability worldwide

The new Valtek GS integrated control valve package provides process plant operators that perfect balance of performance versus cost without compromise to product quality or integrity.

Product Range:

DIN: DN 15 - 150 / PN 16 - 40
AMSE: 0.5” to 6"; pressure class 150 and 300
Body materials: Carbon and stainless steel

Standard live loaded packing systems: TA-Luft/ISO 15848-1 up to +400° C (752°F) operating temperature 

Temperature range: -60°C up to +400°C (-76°F up to 752°F)
End connection: Flanged
Leakage class: IV standard; IV and VI optional
Options: Bellows seal, extension bonnets, low noise and cavitation control trims

Actuation:  Pneumatic diaphragm and electrical linear actuators

Features:

Maximum Capacity Flow Rates: The Valtek GS replaces a long list of forerunners to handle a wide selection of process control applications for high-flow, general service applications in the oil and gas, chemical, power and general service industries. The Valtek GS averages 25% higher flow capacity than comparable globe valves.

Cavitation control / Noise attenuation: The Valtek GS is ideal for general application solutions requiring high Cv, noise abatement, and cavitation control. These trim solutions include unbalance, pressure balanced and MultiStream anti-noise, anti-cavitation control.

Smaller, lighter, cost effective: Achieves maximum-flow capacity that outperforms competing brands with a smaller, lighter, and more cost-effective Valtek GS control valve.

Large-diameter Plug Stem:  Virtually eliminates shaft fail­ures. The heavy-duty stem provides a large surface area to reduce guide wear, thus improving reliability and increasing valve life. When tight shutoff is required, the robust stem can easily absorb actuator thrust and drive the plug securely into the valve’s single-seated trim.

Deep Packing Box: Permits a variety of packing configurations in addition to the standard TA-Luft, live-loaded emission control packing. Packing consists of an upper set and a wiper set. The latter is designed to minimize the amount of fluid on the plug stem. The upper set is positioned far enough away from the wiper set to avoid contamination from the flowing medium.

Double Top-stem Guides: Ensure accurate plug and seat ring alignment. The widely spaced, graphite-lined stainless steel guides provide superior guiding over broad temperature ranges and completely eliminate guide/stem galling.

Contoured Plug Design: Is readily adaptable for modified equal percentage, linear and quick-open flow characteristics. And it can be mated to a variety of trim types, providing excellent rangeability, repeatability and resolution.
