PTFE Coated Lug Butterfly Valve Introduction

PTFE Coated Lug Butterfly Valve is a type of butterfly valve designed for use in highly corrosive and demanding environments. The PTFE (Polytetrafluoroethylene) coating provides exceptional chemical resistance, making it ideal for handling aggressive chemicals, acids, and gases. Its lug-style design allows for easy installation between flanges, ensuring secure connections. This valve offers reliable sealing, low friction, and minimal maintenance, making it suitable for industries like chemical processing, wastewater treatment, and pharmaceuticals.
