PTFE fully lined butterfly valves with split body for high corrossion resistant

PTFE fully lined butterfly valves with split body, suitable for seawater, chemical and other high corrosion medium
Full teflon coated butterfly valves are widely used in harsh enviroment

Teflon lined butterfly valve are designed for handling corrosive, abrasive, or high-purity fluids.
Corrosion Resistance: Teflon fully covered on disc and body, it resists almost all acids, bases, and solvents.
Zero Leakage: The soft Teflon seat provides a bubble-tight seal (Class VI shut-off). Max. Pressure is PN16
Smooth Flow: The lining creates a very smooth surface, preventing media from sticking to the valve walls.
Temperature Limits: Standard PTFE with Max. temperature of 120°C (302°F).

Product Detail

Butterfly valve utilizes the phenolic-backed cartridge seat or Booted seat or vulcanized seat

to tight bubble seal with zero leakage. Butterfly valves works as shut-off valves for control the pipeline open/close. Butterfly valves can also be used for rough throttling with different open position.
