Version 1.0-1996 – "Originator"

Introducing our new flagship product, the PTFE-lined ChemFlyer | CST butterfly valve.

Made in Switzerland to the highest standards, our specially designed liner reduces wear and tear, leading to a longer-lasting, more secure seal.

A modified PTFE liner ensures that the ChemFlyer | CST can securely handle aggressive media, such as chlorine gas, in a range of applications.

The maximised inner bore diameter also offers an optimised through-flow of media, reducing turbulence and minimising operational costs.
