TL20
Our TL20 butterfly valve was designed for general industrial applications. Due to its lug flange design, it can serve as a complete and cost-effective replacement for double flange valves. It offers significant benefits in systems where a line must occasionally be isolated.

Butterfly valve function test
Our valve design is based on years of experience - but we are always looking for ways to further improve the design and choice of materials. Our butterfly valves are currently being put through their paces in a large-scale endurance test where they have to withstand more than 20,000 closing cycles.

Our latest butterfly valve order
12 lug type butterfly valves TL20 with nominal sizes from 65 – 250 were recently assembled at our Sistag plant. Operated by a spring return pneumatic actuator with inductive double sensor. DVGW gas approved and ATEX certified. Along with several knife gate valves, these valves are soon going to be installed in a newly built biogas plant in Switzerland.
