Fluoropolymer-lined butterfly valve
PFA-Lined Butterfly Valves
Catalog-listed DN50–DN900 butterfly valves with a fluoropolymer-lined flow path. Final suitability depends on the exact lining, every wetted material, media chemistry and the combined pressure-temperature duty.
Construction route
A butterfly-valve format with a separated lining system
A two-piece body, lined flow path and multiple operator routes provide a compact butterfly-valve option for compatible chemical-service projects.
- ¼Quarter-turn valve mechanism
A butterfly-valve format offers a compact flow-control or isolation route where the lining and service conditions are compatible.
- LLined media-contact path
The source catalog separates the structural body from the fluoropolymer-lined wetted surfaces.
- AManual or automated operation
Operator selection still requires valve torque, cycle frequency, control signal and environmental data.
