junction with third-party devices and components recommended
and authorized by Bürkert.
▶The applied protection class is encapsulation Ex “m” for coils with
cable connection.
▶The ignition protection type for the optionally mounted terminal
box is “e” for gas and “t” for dust.
▶The faultless and reliable operation of the system assumes cor-
rect transportation, correct storage and installation as well as
careful operation and maintenance. Any other use is regarded as
unauthorized. Bürkert is not liable for any resulting damage. The
user alone bears the risk.
▶Only use the device for its intended purpose.
2.1 Explosion protection approval
The explosion protection approval is only valid if you use the modules
and components authorized by Bürkert, as described in these oper-
ating instructions.
The solenoid coil AC19 may be used only in combination with the
valve types released by Bürkert, otherwise the explosion protection
approval will be terminated. If you make unauthorized changes to the
system, the modules or components, the explosion protection approval
will also be void.

equipment) as well as pneumatically conveyed dust.
▶Clean the device surface by gently wiping it with a damp or anti-
static cloth only.
To avoid the risk of explosion, the following must be observed

Product description
5.2 Solenoid coil with cable outlet
The solenoid coil type AC19 is an electromagnetic valve actuator for
various Bürkert valves. As a so-called top-mounted coil, it is separated
100 % from the valve. The valve is a closed system even if the coil is
removed.
The solenoid coil consists of:
• coil winding,
• coil housing (made from epoxy),
• electrical connection cable,
• bridge rectifier.
Alternating current or direct current control is possible.
The solenoid coil type AC19 is available in a range of ratings distributed
across 2 frame sizes. The interface between the coil and valve is iden-
tical for both frame sizes.
The coil is placed over the core guide tube of the valve and attached
with a nut. It is positively locked to prevent turning relative to the valve.
The electrical connection cable exits perpendicular to the coil axis.
The cable is permanently integrated in the coil. The union nut is not
designed to be removed.
An electrical contact is made between the metal components of the
valve and the coil at the interface between the coil and the valve. All
metal components must be grounded via the protective conductor in
the connection cable.
5.3 Solenoid coil with terminal box
The design of the solenoid coil is identical to the description under
„5.2“, however a terminal box is also installed here (see „Fig. 2“).
The terminal box is certified with the Type Examination Certificate
PTB 15 ATEX 1011 U bzw. IECEx PTB 15.0037 U.
The cable outlet direction can be selected according to the order
requirements. The outlet direction can be changed subsequently,
however this requires a special tool1). Optionally a connection set is
enclosed for additional potential equalization; to do this, observe the
specifications in chapter „8.2“.

8.2 External grounding connection
for terminal box
If solenoid coils feature a terminal box, connection terminals are
enclosed for the external grounding connection.
If the potential equalization is not to be connected by a pipeline or
by the use of a plastic fitting, the connection can be made via the
external grounding connection. Its use is therefore optional and must
be assessed by the operator.
The connection capacity of the ring cable lug is 4-6 mm2. The con-
nection is made as shown in „Fig. 7“.
