ANDERSON GREENWOOD
5910C PRESSURE/VACUUM RELIEF VALVE WITH INTEGRATED
FLAME ARRESTER (ATEX APPROVED)
SPECIAL CONDITIONS FOR SAFE USE (CONTINUED)
All 5910C deflagration elements are rated
for short time burning, tBT not to exceed one
minute in accordance with EN ISO 16852:2016.
These burn times were determined at
atmospheric pressure. If there are operating
conditions which can lead to a stabilized
burning event, additional safety measures are
required. The devices shall be equipped with
temperature sensors in the hood such that
the atmospheric side of the flame cell can be
monitored. These temperature sensors are
installed into the system in such a way that
they trigger the initiation of measures for
the elimination of the stabilized burning (for
example, emergency functions like switching-
off the system, inerting or similar). These
measures must occur within half of the time
for which the flame arrester is short-time burn
proof (0.5 x tBT). See Figure 03 for warning
label showing burn rating, tBT. This requires
that measures must be able to be taken within
30 seconds.
Threaded instrumentation ports, with standard
1/2 NPT threads, are integrated into each hood.
Other instrumentation port thread sizes can be
requested.
If the user requests the addition of temperature
sensors by Emerson, they will either be
installed and shipped threaded into the
appropriate instrumentation port in the
flame arrester hood or shipped separately
with the flame arrester. To install the
temperature sensors that have been shipped
separately, simply remove any protective
packaging from the temperature sensors
and thread the temperature sensors into the
appropriate threaded instrumentation ports
in the flame arrester hood making sure to
follow temperature sensor manufacturer’s
instructions, particularly for wiring.
The temperature sensor shall be installed on
the downstream or unprotected (“hot”) side of
the flame arrester. For end of line deflagration
flame arresters this is the atmospheric side
of the flame arrester and the only location
available. If the temperature sensor is shipped
separately, the user shall be responsible
for installing the temperature sensor in the
appropriate instrumentation port in the hood of
the flame arrester.
If a temperature sensor is not requested with
the flame arrester then the end user shall be
responsible for installation of the temperature
sensor on the unprotected (“hot”) side of
flame arrester. This is the side of the flame
arrester closest to the source of ignition
