ENGLISH
• When planning the application of the device, and during its operation,
observe the general technical rules!
• Take suitable measures to prevent unintentional operation or
impermissible impairment!
• Note that lines and valves must not be unscrewed from systems that
are under pressure!
• Always switch off the voltage supply before working on the system!
• If these instructions are ignored, no liability will be accepted from our
side, and the guarantee on the device and on accessories will also
become invalid!
• Warning! The surface of the electromagnet can become very hot
during continuous operation. Danger of injury!
To ensure that the device will function correctly, and have a
long service life, please comply with the information in these
Operating Instructions, as well as with the application condi-
tions and permissible data given in the Type 5281 data sheet:
Read the voltage, electrical power, type of protection and
current from the rating plate!
Voltage tolerance: ±10%
• Electrical power connection: Instrument socket type 2508 to the tag
connections on the coil (protection class IP 65);
Tightening torque: 1 Nm
• When screwing down the instrument socket onto the coil, ensure that
the flat seal is well seated!
• With impulse coils, pay attention to asynchronous excitation!
Modular, servo-assisted flow valve with servo-diaphragm and
push-over coil
• coil can be locked in 4 x 90° steps, in between which it can be freely
positioned around the armature guide tube
• tightening torque of the fixing screws: max. 5 Nm
• can be mounted in any position, preferably with the magnetic system
at the top
• valve operation A: service port normally closed
• media: neutral fluids and gases which do not attack the valve body
and seal or diaphragm materials
• seal material: refer to rating plate following the nominal diameter
(NBR, EPDM, FPM)
• permissible temperature range of the medium: -10 °C to 100 °C
• max. ambient temperature: + 55°
• the port connections are compatible with the previous model 281/291
Work on the valve should only be carried out by specialist staff
and with the correct tools!
• Clean the piping system before installing the valve!
• Where necessary, connect a strainer upstream to protect against
faults!
• Pay attention to the flow direction (direction of arrow).
• Seal the thread using PTFE tape!
• Ensure that there is the full diameter available at the inlets and outlets
to the valve, and that pilot channels are open!
• When tightening the pipe connections, never use the valve as a lever!
• Be careful of distortion when installing the valve body.
• Faults can be caused by soiling, short circuits and loss of power!
• Attention: Jammed coils can cause coil overheating with AC!
• In case of faults, check the port connections, voltages, type of current
and operational pressure!
