Electric All-Film Fluorine PTFE Sealing Butterfly Valve
- Controls fluid on/off or regulates flow by rotating the butterfly plate
- Designed for harsh corrosive, high-purity, or high-temperature media environments
- Electric Valve SUS304
Product Overview
The electric all-film fluorine butterfly valve is a type of valve that controls fluid on/off or regulates flow by rotating the butterfly plate. The valve seat, butterfly plate, and all media-contacting components are lined with fluoroplastics (such as PTFE, FEP, PFA, etc.). It is specifically designed for harsh corrosive, high-purity, or high-temperature media environments, offering exceptional chemical resistance and long service life. It is suitable for automated control in demanding industrial scenarios.
Product Features
- Ultra-strong corrosion resistance: Fully fluoro plastic lining resists pH 0-14 extreme environments, suitable for strong acids, alkalis, and organic solvents.
- Zero-leakage sealing: Multi-layer elastic fluoro rubber or PTFE composite sealing structure meets ANSI/FCI 70-2 Class VI standards.
- Wide temperature range: Fluoro plastic material temperature range -50°C to +200°C (PTFE); special materials or additional cooling components can achieve higher temperatures.
- Lightweight design: Compact structure, small installation space, weight only 60% of similar metal valves.
- Intelligent control: Electric actuators support switching (ON/OFF) or regulation (4-20mA signal feedback, Modbus communication).

Application
Media Types
- Strong acids (sulfuric acid, hydrochloric acid, nitric acid, etc.), strong alkalis, organic solvents, mixed corrosive media.
- High-purity liquids (pharmaceutical, food-grade media compliant with FDA, GMP standards).
- High-temperature gases or liquids (temperature range adjusted based on fluoro plastic type).
Application Fields
- Chemical industry: Corrosive medium conveying systems.
- Pharmaceutical/Food: Sterile pipelines, high-cleanliness fluid control.
- Environmental engineering: Acid-base wastewater treatment systems.
- Electroplating/Metallurgy: Electrolyte, corrosive gas pipelines.
Installation Requirements
- Pre-treatment: Thoroughly clean the pipeline before installation to avoid scratching the fluoro plastic layer with welding slag or hard particles.
- Alignment: Symmetrically and evenly tighten flange bolts to prevent valve body deformation affecting sealing performance.
- Flow Direction: Valve body arrow direction must align with medium flow direction (bidirectional sealing by default if no arrow).
- Welding Protection: Prohibit welding near the fluoro plastic valve body to prevent high temperatures from damaging the fluoro plastic layer.
- Maintenance Space: Reserve space for actuator operation and maintenance to ensure unobstructed full-open/full-close operation.
