Technical
Data
Approvals
UL/C-UL Listed
Listings and Approvals are based
on DV-5A Valves being trimmed as
described in this technical data sheet
and in conjunction with the use of the
Burkert Type 5282 Solenoid.
For local EMEA regional approvals,
consult with your local distributor.
DV-5A Valve
Components for the 3 in. to 8 in.
(DN80 to DN200) DV-5A Valves are
shown in Figure 1. The DV-5A Valves
are for vertical installations. They are
rated for use at a service pressures of
20 to 300 psi (1,4 to 20,7 bar).
The take-out dimensions are shown
in Figure 3, and flanged connections
are available drilled per ANSI, ISO, AS,
and JIS specifications (Ref. Table A).
Threaded inlet and outlet connec-
tions are available in NPT or ISO 7/1.
Threaded port connections are NPT
threaded.
Valve Trim
The Maximum pressure rating is as
follows:
• Deluge Remote-Resetting, Pressure-
Reducing Trim is 250 psi (16 bar)
dependent on separately ordered
solenoid valve.
When the system pressure is greater
than 175 psi (12,1 bar), provision is
to be made to replace the standard
order 300 psi (20,7 bar) Water Pres-
sure Gauges with separately ordered
600 psi (41,4 bar) Water Pressure
Gauges.
If the addition of an Alarm Control Valve
is desired or required by the local AHJ,
the Alarm Control Valve noted as Item
H in Figure 9 is to be a separately
ordered electronically supervised nor-
mally open valve.
External trim connections are NPT
threaded. EMEA trim is provided with
NPT x ISO 7/1 thread adapters.
Pressure Loss
For the flow characteristics across the
valve when the inlet pressure is below
the set pressure, refer to Graph A
through Graph D and Table B.

copper per ASTM B88.
Design
Criteria
The following items must be consid-
ered and applied accordingly for TYCO
DV-5A Valve with Remote-Resetting,
Pressure-Reducing Trim installations.
NOTICE
The owner is responsible to design into
the system a releasing circuit such that
a Solenoid Valve is properly configured
to enable remote resetting.
The building owner must be informed
of the capabilities and limitations of a
remote-resetting, pressure-reducing
system as it pertains to the possibil-
ity of an inadvertent remote closing
of the DV-5A Valve during a fire condi-
tion. Therefore, personnel responsible
for the fire protection system must be
fully trained on system components
and required actions in the case of an
alarm.
The Control Panel, Detectors, and Pull
Stations are to be installed in accor-
dance with their laboratory listings and
approval.
System piping is to be installed so that
it is self-draining. TYCO Model AD-2
Automatic Drain Valves can be used
to drain low sections of pipe as nec-
essary. For more information, refer to
Technical Data Sheet TFP1632.
