New Neles segmented ball valve for on-off applications combines the material efficient control valve design with the high capacity and proven performance of Neles on-off valve seating technology. Standard units are equipped with cylinder or manual actuators and intelligent on-off valve controllers to ensure excellent and reliable isolating performance
NelesAce is the ultimate solution for basis weight control which is one of the most critical applications for a valve in a paper machine. The unit consists of a reliable V-port segment valve, complete with a high-resolution step-motor-driven rotary actuator, limit switches, and potentiometer.
Neles R-series V-port segment valve is an economical high performance control valve designed for liquid, gas, vapor and slurry control applications - especially with high capacity and wide rangeability requirements. R-series offers light weight, low torque control valves from 1" low capacity models up to 32".
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.
