The connection dimension of actuators for the GEKO 710/720R Series butterfly valve could be made according to ISO5211, American nathional standard or customized.
The valve body, seat and stem all could be coated or lined with PTFE or PA.which have strong chemical-resistance, can be widely applied to such hard environment as: petroleum plant, pharmaceutical, fine chemical industry and so on.The valve performs well at -30℃~110℃ ambient temperature. Thanks to the specific PTFE's low friction, the valve have a longer working life,no matter how frequent open-close operations.
