With valve types 6021, 6022, 6023, 6024, 2821, 2832, 2834
and 2836, the current value I
valve reduces with increasing pre-pressure;
The current value I for the full opening of the valve decreases
2
with increasing pressure drop across the valve.
In the servo-assisted valve Type 6223, the current value I
the start of opening of the valve increases with increasing pre-
pressure;
The current value I for the full opening of the valve increases
2
with increasing pressure drop across the valve.
The valve will not be damaged if a higher coil current than
the value I given in the right-hand column of the table is
2
set with a maximum control signal. It will, however, cause
little or no increase in the flow rate , and will impair the
linearity of the characteristic.
In continuous use, it is possible that this increased current
value cannot be maintained by the current regulator, as a
result of the resistance increase resulting from the
warming of the coil.
