Genebre Presents the pneumatics valve of 2 roads modulante
4 June 2013
Obturador isoporcentual: In the obturador with characteristic isoporcentual each increase of career of the obturador produces a change in the discharge that is proportional to the discharge that flowed before the variation.
Use valves with obturadores isoporcentuales stops:
• fast Processes.
• When the dynamics of the system does not know very well.
• When it requires high rank of control (rangeability) or field of control of discharge that the valve is able to regulate keeping the inherent characteristic curve.
Valve of Simple Seat and 2 roads. The valves of simple seat require of an actuator of greater size so that the obturador closing against of the differential pressesure of the process. The tight closing attains with obturadores provistos of a seat of PPL (304+PPL).
