ChemFlyer | CST – Innovative PTFE Shut-off Valve for Aggressive Media

Tailored for substances such as chlorine gas, hydrofluoric acid, and sulfuric acid, the ChemFlyer | CST from ChemValve-Schmid seamlessly integrates into Warex Valve’s range of valves, immediately expanding the offerings of the Powder and Bulk specialist. Known for its high-performance shut-off valves, Warex Valve ensures safety and tightness even in explosion-prone areas. Custom configurations are crucial for the valve expert in Senden to ensure process-optimized functionality. Hence, the collaboration with ChemValve-Schmid was a natural fit: the Swiss manufacturer has been globally recognized for over 30 years for its modular, PTFE-lined shut-off valves. Like Warex Valve, the Swiss company prioritizes flexible production through its in-house team. The internationally sought-after PTFE shut-off valve ChemFlyer | CST, manufactured to the highest quality standards in Welschenrohr, is now available through Warex Valve.

Construction Advantages

The ChemFlyer | CST provides smooth functionality with corrosive media, allowing ample space for modifications. This is achieved through its advantageous design: the rounded and polished sealing surfaces of the disc reduce torque, enabling the use of smaller, cost-effective actuators and extending the lifespan. The precisely dimensioned, one-piece disc, accurate to the tenth of a millimeter, remains securely anchored in the valve. The injection-molded elastomer inserts ensure maximum tightness. The ChemFlyer | CST is modular from the ground up, individually traceable with a serial number.

Modified PTFE

The ChemFlyer | CST is also available in modified PTFE, offering reduced permeability and extended lifespan at high operating temperatures. With a nominal size range of DN 25–1200, it is compatible with all common drive systems through freely selectable shaft ends. ISO 5211-compliant head flanges allow the direct attachment of actuators, gears, and hand levers. The shut-off valve is suitable for operating temperatures from -60°C to 200°C, compliant with Pressure Equipment Directive 2014/68/EU, ATEX 2014/34/EU, Food (EC) No. 1935/22004, and FDA | TA-Luft regulations.

Quality from Senden

For the valve experts in Senden, the distribution of ChemFlyer | CST enables a targeted expansion of the portfolio for specialized applications in the food, chemical, and pharmaceutical industries. For 60 years, Warex Valve has offered a wide range of shut-off valves, ball valves, sealing systems, and spare parts.
