2503 boost Close is designed for use with type 6712 and type
6724 valves.
▶ Use according to the permitted data, operating conditions and
conditions of use specified in the contract documents and opera-
ting instructions.
▶ Do not use the device outdoors.
▶ The device may be used only in conjunction with third-party
devices and components recommended and authorised by
Bürkert.
▶ Correct transportation, correct storage and installation and
careful use and maintenance are essential for reliable and
problem-free operation.
▶ Use the device only as intended.

▶ Do not make any internal or external changes on the device and do
not subject it to mechanical stress.
▶ Secure the system from unintentional actuation.
▶ Only trained technicians may perform installation and maintenance
work.
▶ The valves must be installed in accordance with the regulations
applicable in the country.
▶ After an interruption, ensure that the process is restarted in a con-
trolled manner.
▶ Observe the general rules of technology.

3.1
Conformity
Type 2503 conforms with the EU Directives according to the EU
Declaration of Conformity (if applicable).

1) with FKM and FFKM the electronics reduces the life time significantly.
2) 3/2-way valves can be connected. In this case, the leak-tightness of the
normally closed connection (NC) is increased. The leak-tightness of the
normally open connection (NO) remains unchanged.
3) Note! If the electronics operating voltage is switched off, the pressure
values drop to the values without electronics specified in the data sheet.

NOTE
3/2-way valves can be connected. in this case, the leak-tightness
of 'the normally closed' connection (nC) is increased. the
leak-tightness of the 'normally open' connection (no) remains
unchanged.
DANGER
risk of injury from high pressure
If the operating voltage (+U
) is switched off (e.g. at the end of
B
operation or due to an emergency stop), the 'active seal effect'
is no longer applicable. The pressure values drop to the default
values of the applied valve (see data sheet).
▶ Pay attention to the maximum permissible return pressure values
and dynamic pressure values stated in the table „3 Technical data".
