Neles ACE R1LW basis weight valve
DN150
Drive NC4K150-ND4KS22
including control box
Basis weight control is one of the most critical applications for a valve in a paper machine. NelesAce is the ultimate offer for this application. The unit consists of a reliable V-port segment valve complete with a high resolution stepper motor driven rotary actuator, limit switches and potentiometer. The unique ability of the NelesACE controller to operate valves with different increments depending on the error between actual and desired flow rate makes it a superior element for basis weight control. Any error can be fixed quickly and accurately with no overshoot. This helps, for example, to shorten the settling time when changing grades.
