butterfly valve

We believe that a butterfly valve should not be treated as a commodity. Much attention has been paid to the design of our valve. For example, our sleeves have a line seal on the shaft. The valve is also equipped with shaft sleeves to prevent wear. Everything is aimed at a long service life without leakage. The leak detection indicates when maintenance is necessary.

And then it comes down to 'easy maintenance'. This has also been well thought out. An indicator on the shaft shows the position of the butterfly, avoiding a common mistake during assembly. The butterfly valve is even available in a special easy maintenance version, which keeps maintenance costs extra low. Like the valve, the engine is also easy to overhaul: a sustainable alternative. The butterfly valve can be fitted with air motors in various diameters – including oversized ones – which simplifies process optimisation.
