Operating principle 2/2-way valve:
A
(NC)
2/2-way valve,
direct-acting, normal output A
unloaded
Type of protection: IP65 in accordance with DIN EN 60529 / IEC
60529 with correctly connected and installed
device socket, e.g. Bürkert Type 2508
Ambient temperature: max. +55 °C
Permitted medium temperature depending on seal material and
coil model:
Seal material Model with High-power
coil or rectifier AC/DC*
Model without elec-
tronics 50 Hz, 60 Hz*
NBR -10 ... +80 °C -10 ... +80 °C
FKM 0 ... +90 °C 0 ... +120 °C
EPDM -30 ... +90 °C -30 ... +100 °C
* Type label information
Permitted media depending on seal material:
Seal material Permitted media
NBR Neutral media, compressed air, water, hydraulic oil
FKM Per-solutions, hot oils
EPDM Oil and grease-free media e.g. hot water
Operating duration
Unless otherwise indicated on the type label, the solenoid system is
suitable for continuous operation.
For the model with a high-power coil a maximum of 6 switching opera-
tions per minute is possible. This concerns devices with the following
power (type label information):
80/6 W
90/7 W 100/9 W
120/8.5 W 120/10 W 130/9 W
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.

5.1 Safety instructions
DANGER!
Risk of injury from high pressure in the equipment!
▶ Before loosening the pipes and valves, turn off the pressure and
vent the pipes.
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 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 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.
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.
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 %.
