PTFE PFA lined butterfly valve with pneumatic actuator
PTFE PFA-lined butterfly valves with pneumatic actuators are available from GMK and meet the highest quality standards in the industry. The PTFE PFA lined butterfly valve is available in a variety of material grades, including cast iron, carbon steel, ductile iron, and stainless steel. Other available material grades include alloy steel. The operational temperature and pressure requirements of the applications determine the material grades that must be used. It has an enhanced disc design, which results in reduced deflection at higher pressures and a tighter in-line seal. This is because the design was improved.
