NFPA COMPLIANCE
NFPA 652 – STANDARD ON THE FUNDAMENTALS OF COMBUSTIBLE DUST – 2016
EDITION
8.9.4 – Equipment Isolation
o 8.9.4 – Where an explosion hazard exists, isolation devices shall be provided to
prevent deflagration propagation between connected equipment in accordance
with NFPA 69.
o 8.9.4.4 – Isolation of Upstream Work Areas. Where a dust explosion hazard
exists, isolation devices shall be provided to prevent deflagration propagation
from equipment through upstream ductwork to the work areas in accordance with
NFPA 69.
NFPA 69 – STANDARD ON EXPLOSION PREVENTION SYSTEMS – 2014 EDITION
CHAPTER 12 DEFLAGRATION CONTROL BY PASSIVE ISOLATION
o 12.2.2.3 FLOW ACTUATED FLAP VALVE
The EM-NRV meets all requirements of this section when installed with all options and
conveying ductwork per 12.2.3.4.6
KEY POINTS
12.2.3.4.2 Requires a locking mechanism which is provided standard.
12.2.3.4.3 Requires an Inspection door which is provided standard.
12.2.3.4.4 Requires an immediate, automatic shutdown of the protected process.
Accomplished with O-EM-NRV-MS Microswitch which is an available option that mounts
on the NRV locking mechanism and sends a signal upon an event.
12.2.3.4.5 and 12.2.3.4.5.1 requires a continuous signal to ensure valve operation is not
compromised by the accumulation of a dust layer on the bottom interior of the valve and
requires an immediate, automatic and orderly shutdown of the protected process.
Accomplished with O-EM-NRV-DLS capacitive style Dust Level Sensor (DLS) which
sends a signal when 0.15”-0.20” of dust has accumulated. The DLS is located in the
airstream and requires an intrinsically safe barrier.
12.2.3.5 Requires System Certification by a recognized testing organization. A.10.4.2.1
allows for European CEN ATEX certification being acceptable.

EM-NRV NORTH AMERICAN SUPPLEMENTAL MANUAL - V2016NRV-ELE
*NFPA 69-2014 (A.12.2.3.4.6) STATES: The minimum design pressure for the ductwork is typically 2 x P
red
because
the pressure wave reflects off the closed valve. Depending on the distance between the flap valve and the enclosure,
pressure piling could further increase the expected peak pressure.
