Features of Pneumatic Actuated PTFE PFA Lined Butterfly Valve
Every Pneumatic Actuated PTFE PFA Lined Butterfly Valve is designed for reliable operation, long service life, and outstanding corrosion resistance. The fully lined body and disc reduce media contact with metal components, helping extend valve durability. Moreover, the fully enclosed bottom shaft eliminates potential leakage paths and reduces the need for additional sealing components. Furthermore, the live-loaded stem sealing system maintains stable sealing performance without manual adjustment throughout the valve’s service life.
Materials and Construction
GMK manufactures industrial valves using premium materials to meet different application requirements. Available body materials include cast iron, ductile iron, carbon steel, stainless steel, and alloy steel. In addition, PTFE and PFA lining materials provide excellent chemical resistance across a wide range of process media. Therefore, customers can select suitable material combinations according to operating temperature, pressure, and chemical compatibility.
Operating Conditions
Our valves are designed to perform reliably under demanding industrial operating conditions. The working temperature ranges from -30°C to 550°C, making the valves suitable for various chemical and industrial processes. Moreover, the corrosion-resistant lining ensures long-term sealing performance in aggressive environments. As a result, customers benefit from improved reliability and lower maintenance costs.
