Stainless steel Pneumatic Control Valve global valve without positioner
Features
1. Top-guided Single Seated Control Valves, compact valve body, less component, esay to maintain.
2. The metal valve plug is suitable for various work situation, comply with the standard of IV level leakage, and soft seal valve plug achieve the standard of VI level leakage.
3. The valve body designed according to the principles of fluid mechanics to be low rsistance equal section flow channel, rated flow coefficient increases 30%. Wide adjustable scope, inherent adjustable ratio is 50: 1. The valve actuator use multiple springs structure, and the height reduce 30%, the weight reduce 30%.
