2 INTENDED USE

Incorrect use of the solenoid valve Type 0290 can be dangerous

to people, nearby equipment and the environment.

▶The device is designed for dosing, blocking, filling and aerating media.

▶Provided the cable plug is connected and installed correctly, e.g.

Bürkert type 2508, the device satisfies protection class IP65 in

accordance with DIN EN 60529 / IEC 60529.

▶Use according to the permitted data, operating conditions and con-

ditions of use specified in the contract documents and operating

instructions. These are described in the chapter entitled „4 Techni-

cal Data“.

▶The device may be used only in conjunction with third-party devices

and components recommended and authorised by Bürkert.

▶Correct transportation, correct storage and installation and careful use

and maintenance are essential for reliable and problem-free operation.

▶Use the device only as intended.

2.1 Definition of term

In these operating instructions, the term “device” always refers to the

solenoid valve Type 0290.

english

Risk of electric shock.

▶Before reaching into the 0290, switch off the power supply and

secure to prevent reactivation.

▶Observe applicable accident prevention and safety regulations for

electrical equipment.

Risk of burns/Risk of fire if used continuously through 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 function is in perfect working order.

Risk of short-circuit/escape of media through leaking screw

joints.

▶Ensure seals are seated correctly.

▶Carefully screw valve and connection lines together.

Opening the valve briefly

If the pressure increases suddenly with the valve closed, the valve

may open for a short time.

▶Take safety precautions as required with hazardous media.

Risk of injury from unintentional activation of the system and an

uncontrolled restart.

▶Secure system from unintentional activation.

▶Following assembly, ensure a controlled restart.

5.2 Before installation

Installation position: Installation can be in any position.

Preferably: Actuator upright.

→Prior to installation check pipelines for dirt and, if required, clean.

Dirt filter: To ensure that the solenoid valve

functions reliably, a dirt filter (≤ 400 µm) must

be installed in front of the valve inlet.

NOTE!

For devices with approval according to the European Gas Appli-

ances Directive it is essential to install the filter.

5.3 Installation

Sealing material must not get into the device.

→Hold the device with a suitable tool (open-end wrench) on the

body and screw into the pipeline.

english

NOTE!

Caution risk of breakage.

• Do not use the coil as a lever arm.

→Observe direction of flow:

The arrow on the body indicates the direction of flow (no function

in opposite flow direction).

5.4 Electrical installation

DANGER!

Risk of injury due to electrical shock.

▶Before reaching into the system, switch off the power supply and

secure to prevent reactivation.

▶Observe applicable accident prevention and safety regulations for

electrical equipment.

WARNING!

Danger of electrical shock if the protective conductor contact

between the coil and body is missing.

▶Always connect protective conductor.

▶Check electrical continuity between coil and body.

Risk of short-circuit or escape of media through leaking screw

joints.

▶Ensure seals are seated correctly.

▶Carefully screw together coil and device socket or valve and

pipelines.

Note the voltage and current type as specified on the label.

Maximum residual ripple for direct current 10 %.
