TAKE-OUT DIMENSIONS
ties where a pre-alarm of a possible fire
condition may allow time for fire extin-
guishment by alternate suppression
means, prior to a sprinkler discharge.
In the event the fire cannot otherwise
be extinguished, the preaction sprinkler
system will then perform as the primary
fire protection system.
NOTICE
The DV-5 Valves with Single Inter-
a
lock Preaction Trim described herein
must be installed and maintained in
compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION (NFPA), in addition to
the standards of any other authorities
having jurisdiction. Failure to do so
may impair the performance of these
devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.
Technical
Data
Approvals
UL and C-UL Listed
FM Approved
Listing and Approvals are based
on DV-5 Valve being trimmed as
a
described in Figures 7, 8, and 9 (i.e.,
Wet Pilot, Dry Pilot, and Electric
Actuation).
DV-5 Valve
A
Components for the 1-1/2 Inch to
8 Inch (DN40 to DN200) DV-5
are shown in Figure 1. The DV-5
are for vertical installations. They are
rated for use at service pressures of 20
to 300 psi (1,4 to 20,7 bar).
The take-out dimensions are shown
in Figure 3, and flanged connec-
tions are available drilled per ANSI,
ISO, AS, and JIS specifications
(Ref. Table A). Threaded inlet and outlet
connections are available in NPT or ISO
7/1. Threaded port connections are
NPT threaded.
NOTE: PN16 flanges are pressure rated
to 16 bar.
Valve Trim
The maximum pressure rating is as
follows:
• Single Interlock Preaction trim Wet
Pilot Actuation is 300 psi (20,7 bar)
• Single Interlock Preaction trim Dry
Pilot Actuation is 250 psi (17,2 bar)
• Single Interlock Preaction trim
Electric Actuation is dependent on
separately ordered solenoid valve
per Technical Data Sheet TFP2180
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 Figures 16, 17, and 18 is to be a sepa-
rately ordered electronically supervised
normally open valve.
External trim connections are NPT
threaded. EMEA trim is provided with
NPT x ISO 7/1 thread adapters.

See subsections Wet Pilot Actuation,

System Air Pressure Requirements
The supervisory air (nitrogen) pressure
is to be 10 ± 2 psi (0,69 plus or minus
0,07 bar). The use of a higher super-
visory pressure is subject to approval
by the authority having jurisdiction,
and it should be understood that the
use of a higher supervisory pressure
may increase water delivery time.
The use of a lower supervisory pres-
sure may prevent clearing the alarm of
the Supervisory Low Pressure Switch
(Item T - Figures 16, 17, and 18), which
is factory set to alarm at 5 ± 1 psi
(0,34 ± 0,07 bar) on decreasing pres-
Valves
a

Valves
a
sure of 10 ± 2 psi (0,69 ± 0,07 bar)
can be provided by any of the follow-
ing methods. Refer to the applicable
data sheet for laboratory approval
information.
• Model G16AC812 (self contained)
Automatic Supervisory Air Supply
described in Technical Data Sheet
TFP1620.
• A maximum 200 psi (13,8 bar) plant
air supply in combination with the
Model AMD-1 Air Maintenance
Device described in Technical Data
Sheet TFP1221.
• A maximum 3000 psi (206,9 bar)
nitrogen cylinder in combination with
the Model AMD-3 Nitrogen Mainte-
nance Device described in Technical
Data Sheet TFP1241.
NOTE: The dew point of the air or
nitrogen supply for a system exposed
to freezing conditions must be main-
tained below the lowest ambient tem-
perature to which the system piping
