Basis Weight Control Valve

For Controlling The Basis Weight Of Paper On Paper Machine. The extreme accuracy needed in basis weight control is achieved by a step-motor driven, backlash-free rotary actua?tor. It performs precise, minimal changes in valve opening with high repeatability and resolution. The rotary actuator is electromechanical. unit When it's time to change grades and set a new basis weight, the control unit and the actuator quickly turns the valve to a new opening range with minimal downtime. (Adjustable speed with time duration; use RS232 and PC). Equipped with pulse train and time duration interface, Fibretec Basis Weight Valve System is compatible with any process computer output. The control unit operates in a response to a control com?mand from a computer or an electronic controller. As an standard feature there is also a push-buttons for manual operation (open and close) and a digital position display. The DCS operation is activated in the "automatic" mode as a standard. Analog output (4-20 mA) can be used in the DCS to indicate valve position. Available in different size  - 2 size, 3 size, 4 size, 5 size, 6 size, 8 size, 10 size, 16 size valves made o f SS-316. Controlling upto 0.5GSM, Gear ratio 1:44 steps 3000, Limit switches 2, O/p Torque 200, 400, 600.
