Product Details

Product overview
Pneumatic membrane lined fluorine control valve is composed of pneumatic membrane actuator and straight-through single-seat fluorine-lined valve. The parts in contact with the medium of the fluorine-lined regulating valve are all high-pressure injection molding process, lined with corrosion-resistant and aging resistant polyperfluoroethylene propylene, and PTFE corrugated pipe sealing to ensure no leakage. It is widely used in chemical, petroleum, metallurgy, pharmaceutical, electric power and other industries to control and regulate the process of acid, alkali strong corrosive medium and toxic, volatile, permeable and other gaseous and liquid media.

Structural features
1. The corrosion-resistant valve cavity, valve core, valve seat and valve stem are all 316 stainless steel, which can resist acid, alkali and strong corrosion;
2. Good sealing performance, using polytetraethylene bellows and packing double seal to ensure no leakage;
3. The leakage amount is small because the valve core and valve seat are soft seals, and the leakage amount is lower than the national IV standard;
4. It adopts light and small multi-spring actuator, which is small in size, light in weight and high in adjustment accuracy;
5. The leakage amount is less than 0.01% of the rated capacity of the valve;
6. The differential belt positioner is less than 1% of the full stroke;
7. Basic error: with positioner: less than ±1% of the full stroke.
