主体材质：不锈钢
标准现场负载系统：TA-Luft/ISO 15848-1， 高温度可达400° C
温度范围：-60°C ~ 400°C(-76°F ~ 752°F)
连接方式：法兰
漏损等 ：标准为IV ；IV 和VI 可选
可选项：膜盒密封、伸长型上阀盖、低噪音和防气蚀切割
执行：气动隔膜和电动线性执行器
特点：
大容量流量：Valtek GS可以替代大部分流程控制产品，应用于大流量的常规应用中，如石油天然气、化工、电力等等。与同款产品相比，Valtek GS的 大容量流量提升了25%。
气蚀调节/噪声衰减：Valtek GS特别适合要求高Cv，噪声控制和气蚀调节的常规应用。这些切割解决方案包括非平衡、压力平衡和多流抗噪、防止气蚀。
更小、更轻、性价比更高：相同 大容量流量产品，Valtek GS体型更小，质量更轻，性价比也更高。
大尺寸塞杆：几乎消除了轴出故障的可能。重载塞杆有较大的表面区域来减少气门导管磨损，从而提高可靠性，延长阀门寿命。如需紧急关停，坚固的塞杆可以承受执行器的推力，并推至阀门的单座切割。
更深的填料盒：除标准TA-Luft，现场装载排放控制填料方式外，支持大部分的填料配置。填料包括上方设备和滑片设备。后者是用来去除塞杆上的液体的。上方设备和滑片设备的距离足够远，以防污染介质。
双重导管：确保精确塞住、阀座对齐。稀疏排列、石墨画线的不锈钢导管使可用温度范围更大，避免导管/塞杆磨损
柱塞形阀芯设计：可适用于修改后的等百分比、线性和快速开启流动特性。以及多种切割类型、优异的变化幅度、重复性和清晰度。
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.
