ASTM A216-WCB Fluorine Lined Pneumatic Control Valve 3/4"-8" PN16 for Corrosive Media

The L202301 series cast steel pneumatic fluorine lined regulating and control valve features a complete fluorine lined structure for both valve body and internal components, providing exceptional corrosion resistance against aggressive media. The metal valve body inner cavity is processed with a toothed surface to ensure optimal bonding with the lining material, enhancing durability and performance.

Valve stem sealing combines PTFE bellows pipe seal with V-shaped PTFE packing, eliminating external media leakage. This unbalanced fully lined fluorine control valve is specifically designed for highly corrosive media applications under low pressure and normal temperature conditions.

• Complete fluorine lined construction with metal/plastic skeleton and PTFE/PFA lining materials
• Exceptional corrosion resistance against acids, alkalis, and high-temperature media up to 200°C
• Advanced stem sealing system combining PTFE bellows and V-shaped packing for zero leakage
• High precision control with 50:1 adjusting ratio and multiple flow characteristics
• Extended service life with toothed inner cavity design for superior lining adhesion
• Versatile operation options including pneumatic, electric, and electro-hydraulic actuators
• Ideal for chemical, petroleum, and metallurgy industries requiring reliable fluid control

This fluorine lined regulating valve is specifically designed for handling highly corrosive media in demanding industrial environments. It is widely used in chemical processing, petroleum refining, metallurgical operations, and other fluid control applications where corrosion resistance, temperature stability, and leak-proof performance are critical requirements.
