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.

English

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).

5 INSTALLATION

Danger!

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.

▶Secure the system against unintentional activation.

▶Following installation, ensure a controlled restart.

English

5.1 Before installation

→Check pipelines for soiling and clean if required.

→Install a dirt trap upstream of the valve

inlet (≤ 500 µm).

5.2 Installation

Any installation position, preferably actuator face up.

note!

▶Ensure that the valve body is not installed twisted.

▶Ensure that seal material does not get into the device.

▶Do not use the solenoid as a lever arm.

→Hold the device on the body using an open-end wrench and

screw into the pipeline.

→Observe pin assignment according to switching function and

identication.

▶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.

Risk of electric shock if protective conductor not connected.

Seal

max. 50 – 60Ncm

→Screw cable plug tight (approved types see data sheet), ensuring

a torque of 50 – 60Ncm.

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.
