2 INTENDED USE
The solenoid valve Type 0283 and Type 0293 is designed for
dosing, blocking, lling and aerating media.
Type 0293 is classied in accordance with DIN EN 161 Group2,
Class B for gas.
▶Use according to the permitted data, operating conditions
and conditions of use specied in the contract documents
and operating instructions. These are described in the chapter
entitled “Technical Data”.
▶Provided the cable plug is connected and installed correctly,
e.g. Bürkert Type 2508, the device satises degree of protec-
tion IP65 in accordance with DIN EN 60529 / IEC 60529.
▶Do not physically stress the device (e.g. by placing objects on it,
using it as a screwing aid, standing on it or using it as a lever arm).
▶The device may be used only in conjunction with third-party devices
and components recommended and authorised by Bürkert.
▶Use device only when in perfect condition and always ensure
proper storage, transportation, installation and operation.
▶Use the device only as intended.
2.1 Denitions of terms
The term "device" always refers to the solenoid valve Type 0283 or
Type 0293.
3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
contingencies and events which may arise during the installation,
operation and maintenance of the devices.
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 device, switch o the power supply

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!
General hazardous situations.
To prevent injury, ensure that:
▶The system cannot be activated unintentionally.
▶Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
▶After an interruption in the power supply or pneumatic supply,
ensure that the process is restarted in a dened or controlled
manner.
▶The device may be operated only when in perfect condition
and in consideration of the operating instructions.
▶The general rules of technology apply to application planning
and operation of the device.

▶Following installation, ensure a controlled restart.
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.
5.2 Fluid installation
Follow the safety instructions under “5.1”.
Installation can be in any position, preferably actuator upright.
→Before installation, clean any possible dirt o the pipelines.
→For Type 0283 install a strainer (≤ 500 µm) upstream of the
valve inlet. Type 0293 DN20 already has the strainer integrated
in the valve.
→With type 0293 DN25, a strainer (<=500μm), e.g. our type
TFU001, which is accessible for maintenance work, must be
installed upstream of the valve in accordance with DIN EN 161
→Seal the pipe connection with PTFE tape.
Attention: The PTFE tape must not get into the device.
→Observe direction of ow (see “Fig. 3”).
NOTE!
Caution risk of breakage.
▶Do not use the coil as a lever arm.
→Hold the device with an open-end wrench on the housing and
screw into the pipeline.
