on the electrical current applied.)
Both solenoid systems are purely mechanical variants and have
identical safety data.
▶The applied protection class is the encapsulation EX mb for
coils with cable connection or encapsulation with increased
safety EX e mb for coils with terminal box.
▶The solenoid coil Type 7..-... is used to actuate valves which
control gaseous or liquid media. The coil is either encapsulated
with the core feed pipe of the fitting or mounted on the core
feed pipe of the fitting and secured with a nut. This always
creates a closed system and the devices may also be used as
a category 2 device to control gas in gas pumps. The valve bod-
ies can be made of metal or polyamide.
▶Correct transportation, proper storage and installation,
and careful operation and maintenance are essential for
ensuring problem-free and reliable operation of the system.
Any other or more extensive usage is considered contrary to
authorized use. Bürkert is not liable for any resulting damage.
