Neles ACE basis weight control valve
RAW DN100
actuator: NC4L-100
incl. control unit
Basis weight control is one of the most critical applications for a valve in a paper machine. NelesAce is the ultimate offering for this application. The unit consists of a reliable V-port segment valve, complete with a high-resolution step-motor-driven rotary actuator, limit switches, and potentiometer. The NelesACE control unit's unique feature to run valve with various step sizes, depending on error between actual and desired flow rate, makes it a superior element for basis weight control. Any error can be eliminated quickly and accurately without overshooting. This helps to reduce settling time during grade change for example.
