April 24, 2023

Pneumatic diaphragm lining PTFE single-seat control valve, is the executive unit in the control instrument. It consists of pneumatic film actuator and straight through the single-seat fluorine plastic valve composed of two parts. As the valve contact with the medium parts are high pressure injection molding process, lined with corrosion-resistant, anti-aging poly FEP (F46), and PTFE bellows sealed, so the valve is widely used in chemical, petroleum , Metallurgy, medicine, electricity and other industries in the acid and alkali corrosive media and toxic, volatile and other gases, the process of media control. Pneumatic diaphragm lining PTFE single seat regulating valve features: 1. Corrosion resistance: Body cavity, valve, valve seat, stem are 316 stainless steel, acid, alkali, resistant to strong corrosion. 2. Good sealing performance: double sealed with corrugated pipe and packing of polytetrafluoroethylene to ensure no leakage. 3. Leakage is small: As the valve core, seat is a soft seal, so the leakage is lower than the national IV level standards. 4. Small and light multi-spring actuator, small size, light weight, high precision.
