Intended use
To ensure the device‘s unobjectionable and safe function as well as
long service life the user must follow the hints given in this operating
manual and maintain the operating conditions and allowed data. Use
and operating of the device must be made according to the generally
recognized rules of the art. Prevent accidental operations or unallowed
interferences by suited measures.
Description
Type 6519I is a 5/2- or 3/2-way-impulse valve mit Namur-flange or
G 1/4-threated port on the working connections (connections 2 and 4).
The connections 1, 3 and 5 are G 1/4-threated ports. In the block-
threated solenoid are integrated a „pull coil“ and a „throw coil“. At the
valve with Namur-flange is a changeable-plate for easy change of
circuit function from 5/2-way to 3/2-way by rotation over 180°.

Manual override (3 positions)
The 3 positions of the manual override are operate with a small
srewdriver.
-
by position 12 are connections 1 to 2 open and 1 to 4 closed.
- by position 14 are connections 1 to 4 open and 1 to 2 closed
- by position N is valve in switching state of outside control.
Attention! Before switch on the valve, ensure the position „N“ of
manual override. Otherwise can be distroyed the coil.
Safety by assembly and working
Work on the unit must only be performed by skilled personnel using
suitable tools!
Note that lines and valves must be unscrewed from systems that are
under pressure.
Always switch off the voltage supply before working on the system!
Take suitable measures to prevent unintentional operation or
impermissible impairment!
- Clean the pipe runs before fitting the valve!
- Observe the direction of flow!
- Can be mounted in any position, preferably with the magnetic system
at the top.
- Never use the valves as a lever when srewing in the pipe
connections!
- Do not subject the valve housing to stress when fitting!
Warning! The surface of the electromagnet can become very hot
during continuous operation. Danger of injury!
Schema of electrical connection
Electrical connection
Voltage, electrical power, pressure range and nominal diameter are
specified an the rating plate; the voltage tolerance is
±10 %.
- Electrical connection with cable plug type 2508 to tag connector of
coil in protection class IP 65; fixing torque 1 Nm.
- Unconditional connect the ground and check the connection!
- When screwing down the cable plug onto the coil, ensure that the flat
seal is well seated!
Attention! Jammed coils can cause coil overheating with AC!
Remarks about the impulse valves
- Electrical connection see schema.
- The impulse valve is working bistabil; in solenoid are 2 coils,
which are excited through electrical impulses.
- An short impulse to the „pull coile“ (terminal 2 and 3) pulled and
hold the core in this state.
- An short electrical impulse to the „throw coile“ (terminal 1 and 3)
compensed the magnetic power and the core falled off to the old
position (before first impulse).
- Attention! Never give simultaneously impulses of both coils!
- No switch other electrical consumers (relais etc.) parallel to the
valve terminals.
- Ensure by parallel-switching of many impulse valves the galvanical
separation of nonworking coiles; otherwise are faults possible.
- Warning! Never use the valve in a duty cycle by 100 % continuously!
Trouble-shooting
Faults can be caused by dirt, short-circuits or interruptions in the
voltage. In the event of fault, check the port connections, voltages, type
of current and operating pressures.
If the valve not operated, please consult the Buerkert-Service.
