ensure that the process is restarted in a dened or controlled

manner.

3 BASIC SAFETY INSTRUCTIONS

These safety instructions do not make allowance for any contingencies

and events which may arise during installation, operation and

maintenance.

Danger – high pressure.

▶Before loosening the lines and valves, turn o the pressure and

vent the lines.

Risk of electric shock.

▶Before reaching into the system, switch o the power supply

and secure to prevent reactivation.

▶Observe applicable accident prevention and safety regulations

for electrical equipment.

Risk of burns/Risk of re if used continuously through hot device

surface.

▶Keep the device away from highly ammable substances and

media and do not touch with bare hands.

english

▶Do not put any loads on the body.

▶For models with ATEX approval follow the safety instructions in

english

Medium leaking through damaged connections.

▶Do not damage sealing surfaces of the body connections.

Danger due to unsuitable screw connections.

▶Use compatible screw connections only.

→Check pipelines for dirt and clean.

→Install a dirt lter before the valve inlet (0,2...0,4 mm).

Installation position: any, actuator preferably upwards.

NOTE!

Caution risk of breakage.

▶Do not use the coil as a lever arm.

Valve body must not be installed under tension.

Sealing material must not get into the device.

→Seal the pipe connection with an elastomer seal or PTFE tape.

Ensure that no sealing material gets into the device.

→Observe direction of ow: from 1 → 2 (from P → A).

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

into the pipeline.

5.1 Installation of coil

WARNING!

Risk of escape of media.

When a sticking nut is loosened, medium may escape.

▶Do not tighten sticking nut any further.

Risk of injury due to electrical shock.

If the protective conductor contact between the coil and body is

missing, there is danger of electrical shock.

▶During installation insert the plastic ring into the body journal. The
