Pneumatic fluorine lined butterfly valve

Detailed analysis of pneumatic fluorine lined butterfly valve, comprehensive technical characteristics, application scenarios, and market data:

1、 Product Definition and Core Features
Pneumatic fluorine lined butterfly valve is a corrosion-resistant valve driven by a pneumatic actuator to rotate the butterfly plate. Its flow components (valve body, butterfly plate, valve seat) are lined with fluoroplastics (such as PTFE, F46), which can withstand corrosive media such as strong acids and alkalis. The main features include:
Full lined fluorine structure: The inner wall of the valve body and the surface of the butterfly plate are entirely covered with fluoroplastic, and the isolation medium is in contact with the metal substrate.
Bidirectional sealing: using fluororubber/PTFE composite sealing ring, with a leakage rating of ANSI Class VI.
Quick opening and closing: 90 ° rotation action, response time<1 second, supports switch or adjustable control.
2、 Technical parameters and structural design
Parameter specification range remarks
Nominal diameter DN50~DN1200 clamp or flange connection optional
Pressure rating PN1.0~PN16 (ANSI 150~300LB) High pressure models require customization
Applicable temperature -40 ℃~180 ℃ Special design can be extended to -50 ℃~200 ℃
Drive mode: Single/double acting pneumatic actuator can be equipped with a locator to achieve 4-20mA adjustment
Structural classification:
Medium line type: suitable for cleaning media, with stable sealing performance.
Double eccentric type: reduces friction and extends sealing life through eccentric shaft design.
3、 Typical application scenarios
Chemical industry: pipeline control for highly corrosive media such as sulfuric acid and hydrofluoric acid.
Environmental engineering: corrosion-resistant valves in flue gas desulfurization and wastewater treatment systems.
Food and medicine: PTFE lining that meets hygiene standards is suitable for sterile environments.
