Soft-Seated Butterfly Valves
Soft-seated butterfly valves have been designed for many different areas of application,
where the focus is not only on outstanding sealing performance but also on cost-effectiveness.
Our soft-seated butterfly valves impress with their flexibility and wear resistance as well as their reliable functionality.
The robust and high-quality design ensures low-maintenance operation, easy handling and a long service life.
The innovative sealing technology in turn guarantees 100% leak-free operation in piping systems.
Our soft-seated butterfly valves therefore not only increase the efficiency and safety of your systems,
but also contribute to a noticeable reduction in operating costs.
In order to meet the different requirements of your applications, we offer soft-seated butterfly valves
in many different versions with a wide selection of different sizes, connections and actuations.
Depending on your requirements, you can choose between different coatings for the housing or different sealing materials for the seat rings, for example.
For special requirements, we have tailor-made solutions and extensive customization options, designed to ensure optimum performance.
The areas of application for soft-seated butterfly valves are diverse and range from general industrial applications to power stations and chemical plants.
They are suitable for a wide range of media, including water, oil, gas and chemical fluids
and are the perfect choice for anyone looking for a reliable and efficient solution for their fluid and gas management systems.
