Stainless steel Pneumatic Control Valve global valve without
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%.

Single seated pneumatic diaphragm control valve use to top guide
structure, and with multi-springs, Compact valve body, having a
S-shape flow passage that features low pressure loss, allows a
large flow capacity, rangeability, and high accuracy flow
characteristics. Valve plug is highly vibration-resistant as it is
held by a top guide section which has a large sliding area.
