english

Type 6213 EV / 6281 EV

4.2 Application conditions

Ambient temperature: max. +55 °C Operating duration: Unless otherwise indicated on the type label,

the solenoid system is suitable for continuous operation

Important information for functional reliability during continuous operation! If standstill for a long period at least 1-2 activations per day are recommended.

Service life: High switching frequency and high pressures

reduce the service life

Permitted medium temperature depending on coil and seal material:

PA/EP

Seal material Medium temperature

Polyamide PA FKM 0 ... +90 °C Epoxy EP (NA38) FKM 0 ... +120 °C Polyamide PA EPDM -30 ... +90 °C Epoxy EP (NA38) EPDM -30 ... +100 °C Polyamide PA NBR -10 ... +80 °C

1) Marking PA and EP under electric connection

Permitted media depending on seal material:

Seal material Permitted media

FKM Per-solutions, hot oils without additives, diesel

and heating oil without additives, detergent solution

EPDM Oil and grease-free liquids, cold and warm

water

NBR Cold and warm water

Gaseous media at low differential pressures (e.g. compressed air and vacuum) can also be actuated in consideration (or due to restriction) of a lower tightness. We recommend prior clarification with our sales office regarding the possible application

5 INSTALLATION

5.1 Safety instructions

Danger!

Risk of injury from high pressure in the equipment!

▶ Before loosening the lines and valves, turn off the pressure and

vent the lines.

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!

Risk of injury from improper installation!

▶ Installation may be carried out by authorized technicians only and

with the appropriate tools!

Risk of injury from unintentional activation of the system and an uncontrolled restart!

▶ Secure system from unintentional activation. ▶ Following installation, ensure a controlled restart.

english

5.2 Before installation

Installation position: any, actuator preferably upwards.

Procedure:

→ Check pipelines for dirt and clean. → Install a dirt filter before the valve inlet (≤ 500 µm).

5.3 Installation

note!

Caution risk of breakage!

• Do not use the coil as a lifting arm.

→ Hold the device with a open-end wrench on the body and screw

into the pipeline.

→ Observe direction of flow:

The arrow on the body indicates the direction of flow.

5.4 Manual emergency actuation

To control the valve manually, the hand lever under the coil must be turned into the vertical position.

note!

Caution!

▶ Do not overturn hand lever! ▶ When the hand lever is actuated, the valve can no longer be switched

electrically.

6 MAINTENANCE, TROUBLESHOOTING

6.1 Safety instructions

Warning!

Risk of injury from improper maintenance!

▶ Maintenance may be carried out by authorized technicians only and

with the appropriate tools!

Risk of injury from unintentional activation of the system and an uncontrolled restart!

▶ Secure system from unintentional activation. ▶ Following maintenance, ensure a controlled restart.

6.2 Installation of the coil

Warning!

Electric shock!

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

secure to prevent reactivation!

If the protective conductor contact between the coil and body is missing, there is danger of electrical shock!

▶ Check protective conductor contact after installing the coil.

Escaping medium!

When a sticking nut is loosened, medium may escape.

▶ Do not tighten sticking nut any further.

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 body

cover so that the protective conductor connection of the coil is connected to the valve body.

Procedure:

→ Connect coil body to the core guide pipe. → Screw on coil with nut. Observe torque.

note!

Device will be damaged if the wrong tools are used!

Always use a wrench to tighten nut. If other tools are used (e.g. pliers), the device may be damaged.

→ Check protective conductor.
