Stainless steel flanged butterfly valve

Stainless steel butterfly valves are ideal for acidic and corrosive liquids and for a wide range of pressures and temperatures.

The stainless steel butterfly valves can be used in many applications and industries such as chemical, beverage, brewing, pharmaceutical, petroleum refining, ultrapure water, paper, mining, nuclear power, irrigation and other industries.

Fergo offers a wide variety of butterfly valves regarding their function, body, certification, application, seat, and much more. We offer you all options and modifications for butterfly valves.

We recommend installing a stainless steel butterfly valve in your new production system. This valve is ideal for handling aggressive media and provides reliable shut-off in demanding environments. The use of stainless steel ensures a long service life and low maintenance requirements.

Stainless steel butterfly valves with actuator

High-quality butterfly valves made of corrosion-resistant stainless steel, which enable precise and fast control through the use of pneumatic or electric actuators. These intelligent solutions are specially designed for applications where reliable and automated shut-off of media is required. Whether in the process industry, food technology or the chemical industry – stainless steel butterfly valves with actuators offer maximum safety and efficiency.
