The D1VW with explosion proof solenoids is based on
the standard D1VW series. The specific solenoid design
allows the usage in hazardous environments.
The explosion proof class is
Ex e mb II T4 Gb
for use in zone 1 and 2 (according to ATEX). Additionally
the solenoids are IECEx compliant.
All explosion proof solenoids are DC design. The valves
for AC operate with integrated rectifier.
For further explosion proof valves please refer to catalogue
HY11-3343.

插件孔可以插入在P-端口。

The diagram below specifies the shift limits for valves
with AC and DC solenoids. The specifications apply to a
viscosity of 40 mm2/s and balanced flow conditions. The
shift limits can be considerably lower at unbalanced flow
conditions. To avoid flow rates beyond the shift limits, a
plug-in orifice can be inserted in the P-port.
