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.

En dan komt het aan op ‘easy maintenance’. Ook daar is goed over nagedacht. Een indicator op de as toont de stand van de vlinder, waarmee een veel voorkomende fout tijdens de montage wordt voorkomen. De vlinderklep is zelfs verkrijgbaar in een speciale easy maintenance uitvoering, die de kosten voor onderhoud extra laag houdt. Net als de klep is ook de motor eenvoudig te reviseren: een duurzaam alternatief. De vlinderklep kan worden voorzien van luchtmotoren in uiteenlopende diameters - ook oversized - wat procesoptimalisatie vereenvoudigt.
