Product Description

PTFE-lined butterfly valves are corrosion-resistant valves specifically designed for conveying and controlling the flow of highly corrosive media. The valve body is fully lined with PTFE, PFA, or FEP, effectively isolating the media from the metal substrate and ensuring long-term stable operation under harsh conditions such as acids, alkalis, salts, and solvents. With a compact structure, rapid opening and closing, and reliable sealing, they are commonly used corrosion-resistant valves in industries such as chemical, pharmaceutical, environmental protection, steel, electroplating, and water treatment.

FAQ

Q1: What media are PTFE-lined butterfly valves suitable for?

A: Suitable for acids, alkalis, salts, highly corrosive chemicals, high-purity media, and corrosive gases.

Q2: Can PTFE-lined butterfly valves withstand high temperatures?

A: The temperature range is generally -20°C to 180°C, depending on the PTFE/PFA/FEP lining material.
