Product Description
Double-Flanged ANSI 150lb Butterfly Valve with PTFE Seat for Chemical Service
The VESON Double-Flanged ANSI 150lb Butterfly Valve with PTFE seat is purpose-built for chemical processing applications requiring full corrosion resistance. The double-flanged body design enables easy installation and removal from the pipeline, while the PTFE seat and PFA-lined disc provide universal chemical compatibility for aggressive acids, solvents, and corrosive media.
Key Features
- Double-Flanged Design: Flanged ends on both sides for secure bolted installation with full gasket sealing, ideal for critical chemical lines
- PTFE Seat: Universal chemical resistance with wide pH range (0-14) and temperature stability to +180°C
- PFA-Lined Disc: Fully encapsulated disc eliminates metal-to-media contact for maximum corrosion protection
- Remote Gear Transmission: Floor-stand mounted gear operator with extended spindle for safe operation away from chemical exposure zones
- Blowout-Proof Stem: Anti-blowout stem design meets API 609 requirements for enhanced personnel safety
