    Neles™ MC V-port segment valves, series R2

    Neles has created a specially designed Series R2 segment valves for 8-19 % medium consistency applications. The valve provides an optimized flow path for medium consistency pulp. The flow path is continuously increased to eliminate restrictions where material may build up. The outlet flange is one size bigger than the inlet to ensure this. V-contoured flow path enables to control small capacities without risk of dewatering.
