2.1 Denition of terms
In these operating instructions the term “device” designates the
Type 6430 solenoid valve.
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.
Risk of injury from high pressure.
▶Before loosening lines and valves, switch o the pressure!
Vent or empty the lines.
Risk of injury due to electric shock.
▶Before working on the device or system, switch o the power
supply. Secure against reactivation.
▶Observe the applicable accident prevention and safety regula-
tions for electrical devices.
2 INTENDED USE
Unauthorised use of the Type 6430 solenoid valve may be dan-
gerous to people, nearby equipment and the environment.
▶The device is designed for controlling, shutting o and dosing
neutral media.
▶If devices are explosion-protected (see type label or additional
plate), also follow the operating instructions for the coil/ pilot
control.
▶With a properly connected and assembled cable plug, e.g.
Bürkert Type 2518, the device complies with degree of
protection IP65 in accordance with DINEN60529 / IEC60529.
▶When using the device, observe the authorised data, operating
conditions and deployment conditions specied in the contract
documents and in the operating instructions.
▶Prerequisites for safe and trouble-free operation are correct
transportation, correct storage and installation as well as careful
operation and maintenance.
▶Only use the device as intended.

Risk of burns and re due to hot device surface if device
operated continuously.
▶Do not touch the device unless wearing suitable protective gloves.
▶Keep the device away from highly ammable substances and
media.
Risk of injury due to malfunctioning valves which operate with
alternating voltage (AC).
If the magnetic core sticks, the solenoid will overheat and cause
the valve to malfunction.
▶Monitor valve function.
Risk of short-circuit/escape of medium due to leaking ttings.
▶Check that seals are correctly tted.
▶Carefully screw valve and connection lines together.
General hazardous situations.
To prevent injuries, observe the following:
▶Use the device only when it is in perfect condition and in accor-
dance with the operating instructions.
▶Do not modify the device.
▶Secure device or plant to prevent unintentional activation.
▶Only trained technicians may perform installation and mainte-
nance work.
▶Following interruption of the process, ensure that the process
is restarted in a controlled manner.
▶Do not mechanically load housing.
▶Observe the general rules of technology.
3.1 Warranty
A precondition for the warranty is that the device is used as
intended in consideration of the specied operating conditions.

4 TECHNICAL DATA
4.1 Operating conditions
The following values are indicated on the type label:
• Voltage (tolerance ± 10%) / current type
• Coil power (active power in W - at operating temperature)
• Pressure range1)
• Body material: Brass (MS), gunmetal (RG)
• Seal material: NBR (BB), PUR + NBR (PB), FKM (FF), EPDM
(AA)
1) The version controlled by external air requires auxiliary pilot air to be at
least 2bar above operating pressure.
The vacuum version requires a minimum pressure dierence of 0.5 bar
and is suitable for rough vacuum only.

Viscosity (standard device): 21 mm²/s
Operating duration: Unless otherwise specied on the type
label, the solenoid system is suitable for
continuous operation.
Service life: High switching frequency and high
pressures will reduce the service life.
Important information to ensure functional reliability during
continuous operation!
During a long downtime it is recommended to actuate at least
1–2 switching operations per day.
Liquids and high dierential pressure may cause violent water
hammers.
4.3 Conformity
The device conforms to the EU directives as per the EU Declaration
of Conformity (if applicable).
4.4 Standards
The applied standards, which are used to demonstrate conformity
with the directives, are listed in the EU type examination certicate
and/or the EU Declaration of Conformity (if applicable).

Fig. 1: Circuit diagram connection of pulse valve
The connection terminals in the cable plug are identied with
the numerals 1 to 3 according to the terminals on the valve.
→Connect pulse valves (variable code CF 02) as shown in “Fig. 1”.
Pulse on Terminal 1 closes the valve, pulse on Terminal 2 opens
the valve.
→Connect standard devices L1/+ and N/– to terminals 1 and 2
independently of the polarity.
note!
Important information:
▶Avoid pulses from being simultaneously generated on both coil
windings.
▶Other consumers (e.g.relays) must not be switched parallel to
the terminals.
▶The coil connection, which is not energised, must be electrically
isolated (open).
▶If 2 or more valves are switched in parallel, ensure that this
requirement is met by using bipolar or multipolar switches.
▶If versions feature a manual override, this can be used only
to a limited extent.

code LF02 or LF03) see operating instructions for Type1060.
