The Type 567 product range from Georg Fischer Piping Systems now also includes DN 350 to DN 600 models for the materials PP-H with models DN 350 to DN400 being available for PVC-U. Thanks to the double-eccentric function principle the contact surfaces between medium and elastomers is reduced. In connection with pressure support from a transition seal, it is possible to achieve an activating torque which is up to 50 % lower, in comparison with centric valves, whereby the plate has no contact with the seal in the open position.
