ATKB Series Fluorine Butterfly Valve features a centerline sealing structure, designed for corrosive fluids and high-purity applications. Its triple-seal system ensures reliability:elastic disc springs dynamically compensates for sealing gaps through preload;pure PTFE sealing ring resists corrosion and provides bidirectional sealing;stem O-ring with pressure blocks blocks axial leakage.Combined with multi-layered sealing design and fluorine corrosion resistance, it is tailored for demanding environments like chemical and pharmaceutical industries.
● Centerline Sealing Structure:optimizes fluid control and adapts to frequent operations and high-precision requirements.
● Triple Redundancy Sealing System:
Elastic disc springs: Pre-tensioned to dynamically compensate for wear.
PTFE sealing ring: Corrosion-resistant and bidirectional sealing.
Stem O-ring + pressure blocks: Axial leakage prevention.
● PTFE-Lined Corrosion Resistance:valve body lined with PTFE to withstand aggressive media (e.g., strong acids/alkalis).
● Multi-Layered Protection Design:combines dynamic compensation, static sealing, and axial blocking for zero-leakage safety.
