PTFE Lined Butterfly Valves
Corrosion-Resistant Solutions for Aggressive Media
Our PTFE-lined butterfly valves provide reliable performance in even the most corrosive environments, ensuring safe and efficient handling of highly aggressive fluids. Designed for bidirectional bubble-tight shutoff, these valves offer high flow capacity (CV values) and minimal leakage. They are ideal for demanding applications in chemical, petrochemical, pulp and paper, and food industries. Valve discs can be fully encapsulated with PFA, or solid PFA discs are available for specialized needs.
