Description: mean flow rate through the valve seat under specified working conditions; Name: valve seat speed
Description: mean velocity of the flow through the valve seat at the specified operating conditions; Name: valve seat velocity
Description: voltage which, together with the rated operating current, determines the use of the device and to which the various tests and the use categories refer. With single pole devices the rated rated operating voltage is generally the voltage over the pole. With multi-pole devices it is generally given as chained voltage; Name: Operating voltage
