PTFE Lined Butterfly Control Valves are ideal for applications requiring reliable performance in highly corrosive environments. Their virgin-grade resins and thick fluoropolymer linings offer exceptional resistance to aggressive chemicals such as chlorine, sulfuric acid, nitric acid, and hydrochloric acid, as well as seawater. These rotary valves regulate flow by rotating a disc 90 degrees to start, stop, throttle, or adjust flow, and can be equipped with pneumatic or electric actuators for rapid shut-off, precise regulation, and remote control.
