note!

Caution risk of breakage!
• Do not use the coil as a lifting arm.

Body with welded sleeve: Use PVDF.

Body with bonded sleeves: Use Tangit special adhesive.

Valve body must not be installed under tension.

Observe direction of flow:
The arrow on the body indicates the direction of flow (no function
in opposite flow direction).

6.4. manual emergency actuation

Caution!

Discharge of medium due to loss of the O-rings!
• If the O-rings are lost, the valve will leak. Medium may be

discharged.

note!

Caution!
• When the manual emergency actuation is locked, the valve can no

longer be actuated electrically.

6.5. electrical connection of the cable plug

Warning!

Risk of injury due to electrical shock!
• Before reaching into the device / equipment switch off the power

supply and secure to prevent reactivation!

• Observe applicable accident prevention and safety regulations for

electrical equipment!

If the protective conductor contact between the coil and body is
missing, there is danger of electrical shock!
• Always connect protective conductor.
• Check electrical continuity between coil and body.

Authorized cable plug e.g.

Type 2508 or other suitable

cable plug in accordance with

DIN EN 175301-803 Form A

Seal

max. 1 Nm

Note the voltage and current type as specified on the type
label.

Procedure:

Tighten cable plug (for permitted types see data sheet), observing
max. torque 1 Nm.

Check that seal is fitted correctly.

Connect protective conductor and check electrical continuity
between coil and body.

The connection terminals in the cable plug are identified with
the numbers 1 to 3 according to the terminals on the valve.

Procedure:

Connect the pulse valves (variable code CF 02).

For direct current versions connect negative terminal to terminal 3.

note!

Important information:
• Avoid emitting pulses simultaneously to both coil windings.
• Do not switch any other consumers (relays, etc.) at the same time

as the terminals.

• The coil connection, to which voltage is not applied, must be gal-

vanically isolated (open).

• If two or more valves are switched in parallel, ensure that this

requirement is met by using 2-pole or multi-pole switches.
