TAKE-OUT DIMENSIONS
NOTICE
The DV-5 Single Interlock Preaction
a
Dry Pilot Actuation Valve described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the NATIONAL FIRE PRO-
TECTION 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.

Approvals
UL and C-UL Listed
FM Approved
Listing and Approvals are based on the
DV-5 Single Interlock Preaction Dry
a
Pilot Actuation Valve being trimmed as
described in Figure 5.
DV-5 Valve
A
Components for the 1 1/2 in. to 8 in.
(DN40 to DN200) DV-5
a
shown in Figure 1. The DV-5
is for vertical installations. It is 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
(See 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 for the
Single Interlock Preaction Dry Pilot
Actuation Trim is 250 psi (17,2 bar).
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 8 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.

System Air Pressure Requirements
The supervisory air (nitrogen) pressure
is to be 10 ± 2 psi (0,69 ±0,07 bar). The
use of a higher supervisory pressure
is subject to approval by the author-
ity 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 pressure may prevent
clearing the alarm of the Supervisory
Low Pressure Switch (Item T - Figure
8), which is factory set to alarm at
5 ± 1 psi (0,34 ± 0,07 bar) on decreasing
pressure. The supervisory air supply
pressure 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
Valves are
air supply in combination with the
Valves
a
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 maintained below the
lowest ambient temperature to which the
system piping will be exposed. Introduc-
tion of moisture into the system piping
can create ice build-up that could prevent
proper operation of the system.
The Supervisory Low Pressure Switch
(Item T - Figure 8) is factory set at
5 ± 1 psi (0,34 ± 0,07 bar) on decreas-
ing pressure. The Pressure Relief Valve
(Item S - Figure 8) is factory set to fully
open at 25 ± 2 psi (1,72 ± 0,14 bar) and
it begins to crack open at a pressure of
about 18 psi (1,24 bar).
