Features:.
PTFE/PFA Seat Lug Butterfly Valve is a valve commonly used in industrial applications requiring flow control. The valve is designed with a disc-shaped element that rotates around its axis. This disc is located in the center of the valve body and is connected to a shaft operated by a lever. The lockable stem feature of this valve means that once the valve is set to the desired position, the stem can be locked in place. This adds an extra layer of security to the valve, preventing unauthorized flow manipulation. The valve body and disc are made of stainless steel 304 or 316, which is corrosion-resistant and durable. The seat is lined with EPDM or PTFE, these materials have excellent sealing performance and corrosion resistance. The lug end connection of the valve also facilitates installation or removal on the pipeline without dismantling the entire piping system.
