4.2 application conditions
Ambient temperature: max. +55 °C
Operating duration: Unless otherwise indicated on the type label,
the solenoid system is suitable for con-
tinuous 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

EPDM Oil and grease-free liquids, cold and warm
water
NBR Cold and warm water
2)
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

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.

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.
