PVDF Butterfly valve 243 DA

The Georg Fischer PVDF Type 243 DA is a pneumatic double-acting lug-style butterfly valve engineered for industrial chemical and high-purity fluid handling. Constructed with a corrosion-resistant PVDF disc, PP-GF30 housing with integrated SS316 threaded lug inserts, and high-grade FKM seals. The assembly is driven by a lightweight PP-GF pneumatic double-acting actuator with an integrated NAMUR interface (VDI/VDE 3845), delivering a 90° rotation time of 1–2 seconds at 4.2 bar control pressure. Equipped with a visual position indicator, it enables secure end-of-line installation and reliable bi-directional isolation in demanding process media.
