Pneumatic fluorine lined ball valve

Detailed analysis of pneumatic fluorine lined ball valve:

1、 Product definition and core functions
Pneumatic fluorine lined ball valve is a corrosion-resistant valve that drives the ball to rotate through a pneumatic actuator, specifically designed for regulating or cutting off corrosive media such as strong acids and alkalis.
Its core features include:
Full lined fluorine structure: The valve body cavity and sphere are lined with fluoroplastics such as perfluoroalkoxy (F46) and PTFE, which have extremely strong corrosion resistance.
High sealing performance: Bubble level sealing (leakage ≤ 0.01 × DN mm3/s) is achieved through V-shaped PTFE packing and compression sealing technology.
Explosion proof design: An anti-static device is installed between the valve stem and valve body, suitable for flammable and explosive environments.
2、 Technical parameters and structure
Parameter specification range remarks
Nominal diameter DN15~DN300 (partially supports DN400) flange/thread/clamp type connection
Pressure rating PN1.0~4.0MPa (ANSI 150~300LB) High pressure models require customization
Suitable for temperatures ranging from -40 ℃ to+180 ℃. Special treatment type can reach temperatures up to -50 ℃ to+200 ℃
Drive mode: Single/double acting pneumatic actuator can be equipped with a locator to achieve 4-20mA adjustment
Key structure:
Floating ball design: The ball and valve stem are integrated to avoid detachment caused by pressure changes.
Execution mechanism: GT/AT series piston type, output torque 32~3000N · m.
3、 Typical application scenarios
Chemical industry: pipeline control for highly corrosive media such as sulfuric acid and hydrofluoric acid.
Pharmaceutical field: Delivery of acid-base solutions in sterile environments.
Environmental engineering: Corrosive wastewater treatment system containing solid waste.
