NelesAce™
Superior element for basis weight control
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.
Features
- 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.
