motorized (GEMÜ 498) operators. The pneumatic actuators can be fitted with
pilot valves, electrical position indicators and positioners. In this way, the new
butterfly valve can be integrated in any automated system. Smaller operators can be used due to the reduced torque which results in lower purchase and operating costs. Areas of application for GEMÜ 490 The TFM liner of the butterfly valve provides a very high resistance to chemicals. The butterfly disc is made from stainless steel or PFA-encapsulated stainless steel. The butterfly valve is used in all applications where corrosive liquids and gases are to be controlled. Typical examples are:
* Chemical industry
* Mining and metal extraction
* Steel works
* Treatment of highly corrosive waste waters
* Treatment and distribution of ultra-pure water in pharmaceutical installations and in the semiconductor industry Thanks to its construction, it can also be used in explosion endangered areas. The butterfly valve has also been approved for applications up to 200°C in
