PTFE butterfly valve
The PTFE-lined butterfly valves have been developed with a minimum of 3mm thick PTFE lining to ensure an optimum level of protection. The PTFE-lined butterfly valves are available in wafer and flanged versions with connections of PN10/16/150lbs from DN40-DN300. The PTFE-lined butterfly valves can be controlled with a hand lever, a pneumatic actuator, and an electric actuator.
Automated PTFE coated butterfly valve: pneumatic & electric
The butterfly valve can be installed by ISO 5211 standards. Fergo Armaturen GmbH has a wide range of automation options at its disposal. Fergo Armaturen has extensive experience in the field of automation technology.
