Burkert Type 2836 - Manual (Page 2)

1. OPERATING INSTRUCTIONS
The operating instructions contain important information.
• Read the instructions carefully and follow the safety instructions
in particular, and also observe the operating conditions.
• Keep the instructions in a location where they are available to
every user.
• The liability and warranty for the proportional valve are void if the
operating instructions are not followed.
2. INTENDED USE
The direct-acting proportional valve can be used as an actuating
element for the process control.
• Operate only when in perfect condition and pay attention to correct
storage, transportation, installation and operation.
2.1. Predictable misuse
• Do not use in potentially explosive areas.
• Do not use outside.
• Do not make any internal or external changes.
3. BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any contin-
gencies and events which may arise during installation, operation
and maintenance.
WARNING!
Danger – high pressure!
• Before loosening lines or valves, turn off the pressure and vent
the lines.
Risk of burns/risk of fire if used continuously through hot
device surface!
• Keep the proportional valve away from highly flammable sub-
stances and media and do not touch with bare hands.
• Do not obstruct the heat release required for operation.
To prevent injury, ensure the following:
• Secure equipment/device from unintentional actuation.
• Only trained technicians may perform installation and mainte-
nance work.
• After an interruption in the power supply, ensure that the pro-
cess is restarted in a controlled manner.
• Observe the general regulations of technology.
Electrostatic sensitive components/modules!
Observe the requirements in accordance with EN 61340-5-1 and
5-2 to minimize/avoid the possibility of damage caused by a sudden
electrostatic discharge!

5. INSTALLATION
WARNING!
Risk of injury from high pressure in the equipment.
• Before loosening lines or valves, turn off the pressure and vent
the lines.
Installation position: any position, preferably with actuator above.
→
Clean pipelines and flange connections.
→
Install dirt filter in the direction of flow in front of the valve
(mesh size 0.02 – 0.4 mm; according to orifice).
WARNING!
Danger from medium!
• Make sure that the supplied seal fits properly.
→
Insert seal into valve.
NOTE!
• The proportional valve must not be removed and the central
adjusting screw must not be adjusted.
Screwing in pipeline:
NOTE!
• Use suitable tool (open-end wrench)
and do not use coil as a lever arm.
→
Hold the proportional valve on the fluid
housing using an open-end wrench.
→
Screw in pipeline.
→
Check installation for leaks.
