Authorized use
2 AUTHORIZED USE
Non-authorized use of the solenoid coil Type 7..-... may represent
a hazard to people, nearby equipment and the environment.
▶ The device may be used only for the applications designated in
chapter “Application conditions” and in conjunction with third-
party devices and components recommended and authorized by
Bürkert. Follow the directions of these operating instructions as
well as the operating conditions and authorized data specified in
the chapter entitled “Application conditions”.
▶ The device is used exclusively as a solenoid valve for media
permitted according to the data sheet and for use in explosion
group IIC, category 2G and temperature class T4 or T6
(see specifications on the approval plate).
▶ The solenoid coil is available in two mechanical designs:
- Open / Close version
- proportional acting version (solenoid core opens depending
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.
The user alone bears the risk.
▶ Use the device only for its intended purpose.
2.1 Restrictions
If exporting the system/device, observe any existing restrictions.
2.2 Explosion protection approval
The EX approval is only valid if the modules and components autho-
rized by Bürkert are used as described in these operating instructions.
The solenoid coil Type 7..-... may be used only in combination with the
additional components released by Bürkert, otherwise the EX approval
will be voided! If any unauthorized changes are made to the device,
modules or components, the EX approval will also be voided.
