CST PTFE butterfly valve for aggressive media

Warex Valve is known for its high-performance shut-off valves, which guarantee safety and tightness even in explosion-protected areas. Customer-specific configurations play a decisive role for the valve expert in ensuring process-optimised functionality. The cooperation with ChemValve-Schmid was therefore an obvious choice: the Swiss manufacturer has been world-renowned for its modular, PTFE-lined butterfly valves for more than 30 years. Like Warex Valve, the Swiss company relies on flexible production by its own team of employees.

The ChemFlyer | CST PTFE butterfly valve is in demand internationally, is manufactured in Welschenrohr to the highest quality standards, and is now also distributed by Warex Valve.

The ChemFlyer | CST offers smooth functionality when used with corrosive media and plenty of scope for modifications. These result from the advantageous design: the rounded and polished sealing surfaces of the disc reduce the torque and allow the use of smaller, less expensive actuators, and extend the service life. The one-piece disc, which is precisely dimensioned to a tenth of a millimetre, remains securely anchored in the valve. The injection-moulded elastomer inserts ensure maximum tightness. The ChemFlyer | CST has a modular design from the ground up and is individually traceable with a serial number.

The ChemFlyer | CST is also optionally available in modified PTFE, which achieves reduced permeability and extends the service life at high operating temperatures. The ChemFlyer | CST has a nominal diameter of DN 25-1200 and is compatible with all common drive systems thanks to freely selectable shaft ends. The ISO 5211-compliant head flanges allow direct attachment of actuators, gearboxes, and hand levers. The butterfly valve is suitable for operating temperatures from -60°C to 200°C and complies with PED 2014/68/EU, ATEX 2014/34/EU, Food (EC) No. 1935/22004, and FDA | TA-Luft.
