The Type 6518 is a servo-assisted 3/2-way valve and the Type 6519 is a 3/2,
5/2 or 5/3-way valve. Together, they form a product line. The valves can beused individually or in blocks. The valves work without a continuous air consumption and are used for the pneumatic control of double or single-acting
actuators. The use of high quality materials makes it possible to use thesevalves in the open air and under chemical atmospheres. The product line
contains units with Ex-Approvals and NAMUR flange interface.

• The units may only be used in potentially explosive atmospheres in the manner approved by the admission board, i.e. the permissible maximum electrical values must be observed.
• The valve is intended for operation on 24 V DC outputs via the intermediate switching of a corresponding

The intrinsically-safe Type 6519 Ex ia valve consist of an intrinsically-safe pilot control and a pneumatic
amplifier. The diaphragm-controlled valve seats work with very low friction, ensuring reliable switching of thevalve, even after long shut-down periods.

For general technical data, see “1. General technical data” on page 4.
The valve, made of high-quality polyamide, can be operated as a 5/2 or 3/2-way valve by varying the mounting position of the side changeover plate. The NAMUR flange pattern enables simple field mounting directlyon the pneumatic actuator.

• The maximum medium temperature may never exceed the permissible temperature class (T4 135 °C, T5

The valve bodies are identical to those of the standard variants type 6519 NAMUR. The difference between
the types is in the coils, which are designed and approved differently. By changing the coil on the valve
housing, conversion from non-Ex operation to Ex operation (or vice versa) is very easy. Coil versions withmoulded cable are plugged over and can be locked in 4 × 90° offset positions and positioned as required in
between.

• The units may only be used in potentially explosive atmospheres in the manner approved by the admission board, i.e. the permissible maximum electrical values must be observed.
• The valve is intended for operation on 24 V DC outputs via the intermediate switching of a corresponding
intrinsically-safe operating resource (isolating module or barrier).
The intrinsically-safe Type 6519 Ex ia valve consist of an intrinsically-safe pilot control and a pneumatic
amplifier. The diaphragm-controlled valve seats work with very low friction, ensuring reliable switching of thevalve, even after long shut-down periods.
Type 6519 NAMUR Ex ia is used for pneumatic control of double- or single-acting actuators with NAMUR
flange. The operating principle can be changed by simply turning the changeover plate. In the 3/2-way
function, exhaust air is returned to the spring chamber of the valve actuator. The diaphragm-controlled valve
seats operate with extremely low friction and switch reliably even after long downtimes and at ambient temperatures below zero degrees Celsius. The valve operates without constant air consumption.

Throttle plate for NAMUR version
With type 6519, it is possible to throttle the exhaust air at the exhaust connections R or S. This functionality reduces the travel speedof the connected actuators (process valves, cylinders, etc.). The throttling function can be achieved either by using the accessories
available from Bürkert or by using commercially available throttles suitable for the process environment. In this case, the throttle ismounted on the threaded connection of the housing (connection 3; 5).
Note:
The throttle plate is installed between the actuator and the NAMUR valve.

Converting plate for NAMUR version
The converting plate with silencer is suitable for use with 5/2- and 5/3-way NAMUR valves as a 3/2-; 3/3-way valve. The function NC
can be changed to NO by turning the converting plate by 180°.
If a throttling is required, a standard throttle must be installed at threaded connection R/5 or S/3.
Note:
The converting plate is installed between the actuator and the NAMUR valve.
