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.

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°).
