PTFE Lined Butterfly Valve

Peter PTFE Lined Pipe is a leading manufacturer and supplier of PTFE, FEP, and PFA Lined Butterfly Valves with its headquarters located in Africa, and well-known for offering corrosion-resistant and high-performance lined Valves. Butterfly valves with a PTFE coating have a PTFE-coated disc to resist chemical attack and offer smooth operation. PTFE seal butterfly valves employ a PTFE-lined seat to create a tight, leak-free seal, perfect for treating aggressive media. Both styles work by rotating the disc 90 degrees to control flow, providing uniform sealing and reliability in corrosive industrial applications.

What is PTFE Lined Butterfly Valve?

A PTFE Lined Butterfly Valve is a flow control device that is used to control fluids and has a disc supported on a rotating shaft. The PTFE (Polytetrafluoroethylene) is lined inside the internal surfaces, which is a highly resistant chemical material to shield the valve from abrasive or corrosive media. This lining provides durability, minimizes maintenance, and increases performance in extreme environments. PTFE lined butterfly valves are used extensively in industries such as chemical processing, pharmaceuticals, and water treatment where reliability and corrosion resistance are essential.
