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.
