New plastic butterfly valve

With double eccentric operating principle

The same product that has fascinat­ed our customers for two years in the smaller dimensions is now also available in DN250 and DN300: the plastic butterfly valve type 567/568 with the double eccentric operating principle. Compared to the conventional centric operating principle used in the past, these new double eccentric valves have a lower actuating torque.

The economic advantage of this innovation is that smaller, approximately 20 % cheaper actuators can be used.  In addition, the double eccentric valve has less wear and tear because the disc moves away from the seal quickly when opening. In the open position, the disc does not touch the passage seal. This means there is less chance of incrusta­tion or impurities attaching
