Safety Instructions; Pneumatic Connection - Burkert 6516 Manuel D'utilisation

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.
5.5 Materials
The seal materials depend on the housing materials:
Housing PA
material anodized
Seal NBR, PUR
material
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).
Control pressure: at least 70 % of the operating pressure to
port 1 (minimum control pressure 2.5 bar)

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.

→
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°).
→
Screw down the coil with
a nut using an open-end
wrench (the device may be
damaged if other tools are
used, e.g. pliers).
Observe tightening torque of
max. 5 Nm.

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!

6.3 Pneumatic connection

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.
Installation position: any, preferably with solenoid system face up.
Before connecting:
→
Check whether hose lines are dirty and clean.
→
If required, install a dirt filter upstream of the valve inlet (≤ 500 µm).
Pneumatic connection:
→
Hold the device by hand on the housing and connect to the hose
line. Do not exceed the standard screw-in depth.
→
Seal with PTFE tape or elastomer seal.
→
Observe allocation of the connections
(see Chapter "4.1.1 Connections", page 4).
→
Align hose lines.
Type 6516-6519
→
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.
