SIGEVAL is proud to announce releasing to the market 2 new types of butterfly valve named as:
– BBNV(w) in the range of DN 40 to 1200 series 13 according to the EN 558-1
– FFNV(w) in the range of DN 40 to 1000 series 14 according to the EN 558-1
The main features of these two valves are: Strong design, long life time, vulcanized seat, several options for material components, high thickness coating, exchangeable components with other Sigeval designs.
The internal surface of the valve in contact to the fluid, is covered with rubber so the disc and body is fully tight. Also, rubber offers advantage of high resistance to corrosion if we compare it to just internal coated bodies.
Main markets are: water distribution, naval industry, gas and cooling systems and also cheaper alternative, in some cases, to double eccentric valve.
