FAW-D-PF AW Pneumatic PTFE Fluorine Lining Flanged Butterfly Valve
FAW-D-PF AW Pneumatic PTFE Fluorine Lining Flanged Butterfly Valve
The FAW-D-PF AW Pneumatic PTFE Fluorine Lining Flanged Butterfly Valve combines robust AW pneumatic actuator performance with a high-quality PTFE-lined valve body. Designed for industrial automation, this valve provides reliable ON/OFF and modulating control in corrosive and demanding environments. Its flanged connection allows for easy installation in pipelines ranging from DN50 to DN1400, while the PTFE lining ensures chemical resistance and minimal leakage. The valve features durable stem and disc materials, making it suitable for high-temperature and high-pressure applications. Optional accessories, including limit switches and positioners, enable precise remote monitoring and control.
