1.2 Definition of the term "device"
The term "device" used in the instructions always refers to the
Type 6516 – 6519.
2 INTENDED USE
Incorrect use of the solenoid valve Type 6516 – 6519 may be a
hazard to people, nearby equipment and the surrounding area.
▶The device is used exclusively as 3/2, 5/2 or 5/3-way solenoid valve
for the media permitted according to the data sheet of the corre-
sponding type.
▶Provided the cable plug is connected and installed correctly,
e.g. Bürkert Type 2506 (for Type 6516/6517) or Type 2508
(for Type 6518/6519), the device satisfies degree of protection IP65
in accordance with DIN EN 60529 / IEC 60529.
▶In a hazardous area, the device may be used only in accordance
with the specification on the separate Ex type label. For the use,
observe the additional information enclosed with the device with
safety instructions for the EX area.
▶Devices without a separate Ex type label may not be used in a
potentially explosive area.
▶Use according to the authorized data, operating conditions and condi-
tions of use specified in the contract documents, the data sheet and
the operating instructions.
▶Correct transport, correct storage and installation as well as careful use
and maintenance are essential for reliable and problem-free operation.
▶Use the device only for its intended purpose.

3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any contin-
gencies and events which may arise during assembly, operation and
maintenance.
Danger – high pressure!
▶Turn off the pressure and vent the lines before loosening lines or
valves.
Risk of electric shock!
▶Before reaching into the device or the equipment, switch off the
power supply and secure to prevent reactivation!
▶Observe applicable accident prevention and safety regulations for
electrical equipment!
Risk of injury from greatly accelerated device parts!
▶Before pressurizing the valve, check that all screw connections
and screw joints are tight and secure.
Risk of burns/danger of fire during long-term operation due to
hot device surface!
▶Keep the device away from highly flammable substances and
media and do not touch with bare hands.
Risk of injury due to malfunction of valves with alternating
current (AC)!
Sticking core causes coil to overheat, resulting in a malfunction.
▶Monitor process to ensure flawless functioning.
To prevent injuries/damage:
▶Never adjust the screws which are locked with red paint.
▶Do not make any internal or external changes to the device and
safeguard against unintentional actuation.
▶Installation and maintenance work may be carried out only by autho-
rized technicians with the appropriate tools.
▶After an interruption in the electrical or pneumatic supply, ensure
that the process is restarted in a defined or controlled manner.
▶Do not subject the housing to mechanical loads.
▶Observe the general accepted technical rules.
3.1 Restrictions
If exporting the device, observe any existing restrictions.

1) Observe temperature restrictions on account of approvals.
2) To prevent the expanded compressed air from freezing, its pressure dew
point must be at least 10 K lower than the medium temperature.
Important information for functional reliability during continuous
operation!
If the equipment is switched off for a long period, it is recom-
mended to activate the valves at least 1-2 per day.
Service life:
High switching frequency and high pressures reduce the service life.
The valves operate maintenance-free.

5.6 External control pressure
If valves are designed for auxiliary control air, the compressed air
supply must be connected to port 12 or 14 (control pressure port).

6 ASSEMBLY
6.1 Safety instructions
DANGER!
Risk of injury from high pressure in the system!
▶Turn off the pressure and vent the lines before loosening lines or
valves.
Risk of injury due to electrical shock!
▶Before reaching into the device or the equipment, switch off the
power supply and secure to prevent reactivation!
▶Observe applicable accident prevention and safety regulations for
electrical equipment!
WARNING!
Risk of injury from greatly accelerated device parts and uncon-
nected whiplashing compressed air hoses!
▶Before pressurizing the valve, check that all screw connections
and screw joints are tight and secure.
Risk of injury from improper assembly!
▶Assembly may only be carried out by authorized technicians and
with the appropriate tools!
Risk of injury from unintentional activation of the system and
uncontrolled restart!
▶Secure system against unintentional activation.
▶Following assembly, ensure a controlled restart.
6.2 Installation of the pilot valve
WARNING!
Risk of injury from leaking valve.
▶Ensure that the O-rings/seals are correctly seated in the valve.
Overheating, risk of fire!
Connection of the coil without pre-assembled valve will result in
overheating and destroy the coil.
▶Connect the coil with pre-assembled valve only.
Danger due to electrical shock if coil incorrectly installed!
▶During installation ensure that the coil is situated firmly on the
housing cover so that the protective conductor connection of the
coil is connected to the valve housing.
NOTE!
Caution risk of breakage!
• Do not used coil as a lever arm.

6.2.1 Installation of the pilot valve Type 6106 (for
valve type 6516 / 6517)
0 = rest position
1 = switching
position
→Installation always in the
position shown; if required,
turn coil by 180 °.
→Screw the housing of the pilot
valve to the housing of the
main valve using 2 screws.
Observe tightening torque of
max. 0.5 Nm.
→Mount solenoid coil and
screw down using M2 screws.
Observe tightening torque of
max. 0.15 Nm.
6.2.2 Installation of the pilot valve Type 6014
(for valve type 6518 / 6519)
Manual control
(can be locked
by pressing and
turning)
→Screw the housing of the pilot
valve to the main valve.
Observe tightening torque of
max. 1.5 Nm.
→Connect the coil to the core
guide tube.
The coil can be turned
by 4 x 90° (for block
assembly only 2 x 180°).
