NelesAce™ basis weight control valve
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.
Applications
- Paper machines basis weight control
