Tight closing with manipulated variable
With this function the valve can be moved to its seat with maximum
actuating power (maintained contact of the piezovalves). The tight clo-
sing function can be activating on one side only or for both end posi-
tions. YCLS is activated when the setpoint is below 0.5 % or above
99.5% of the setpoint flow.
