The invention relates to a method for determining polymeric product properties (), wherein a prediction model () is provided for calculating polymeric product properties () based on production parameters on a computer system, which production parameters comprise formulation portions () specifying raw material portions for polymeric production and comprise processing parameters () specifying process properties during polymeric production, wherein user input is provided to the computer system, which user input comprises user production parameters () specifying a set of production parameters, user product parameters () specifying polymeric product properties and a proximity metric for quantifying conformity with the user product parameters (), wherein the computer system applies the user production parameters () to the prediction model () to calculate resultant product properties (), wherein the computer system applies the proximity metric to the resultant product properties () with respect to the user product parameters () to determine at least one proximity value indicating a match between the user product parameters () and the resultant product properties (). The invention also relates to a corresponding computer system for determining polymeric product properties.

Method and computer system for determining polymeric product properties

The invention relates to a valve comprising a valve housing having a valve inlet and outlet, a valve seat arranged in the direction of flow of the fluid between the valve inlet and outlet, a closure means which is movably arranged in the valve housing, and has a first side and a second side, wherein the closure means closes off the valve seat tightly when the valve is in the closed state, a balancing opening for producing a pressure compensation between the first side and the second side of the closure means, and at least one control actuator, wherein the control actuator closes off the balancing opening of the closure means in a closed position and frees the balancing opening of the closure means in an open position so that the closure means frees the valve seat as a result of a pressure compensation via the balancing opening.
