Features and Advantages
● Corrosion-resistant lined butterfly valves are designed for controlling and isolating corrosive media.
● Optional square universal flange valve body type available.
● Fully lugged valve body is available.
● Fully lined valves are strongly recommended for abrasive and corrosive applications that require reliable performance, tight shut-off, consistent torque, and maintenance-free operation.
● PTFE, PFA, FEP, and other fluoropolymers are produced using original resins from well-known brands.
● Especially for lined valves, factors such as lining thickness, resin quality, and manufacturing technology have a significant impact on valve performance and service life.
● Can be operated with a handle, worm gear drive, electric actuator, or pneumatic actuator.
