Valve Trim
The Vertical Electric Actuation Trim
(Fig. 3A/3B) and Horizontal Electric
Actuation Trim (Fig. 5) form a part of
the laboratory listings and approvals
for the DV-5 Valve and are necessary
for its proper operation.
Each package of trim includes the fol-
lowing items:
• Water Supply Pressure Gauge
• Diaphragm Chamber
Pressure Gauge
• Diaphragm Chamber Connections
• Manual Control Station
• Main Drain Valve
• System Drain Valve
• Alarm Test Valve
• Automatic Drain Valve
The following items are included in the
Pre-trimmed Valve Assembly and can
be ordered separately for the valve
trim:
• Model BFV-N Butterfly Valve
• Waterflow Pressure Alarm Switch
(PS10-2)
• Figure 577 Grooved Coupling
To ease field assembly of the trim ar-
rangement, the vertical trim compo-
nents are provided partially assembled
as shown in Figure 3B.

The trim arrangement is provided with
galvanized, black, or brass nipples and
fittings. The galvanized and brass trim
are intended for non-corrosive or cor-
rosive conditions, whereas the black
trim is principally intended for use with
AFFF systems.
NOTE: 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 Pressure
Gauges, shown in Figure 3A/3B and 5
with separately ordered 600 psi (41,4
bar) Water Pressure Gauges.
The Electric Actuation Trim is required
for electric operation of the DV-5 Valve
by a detection system consisting of
electrical devices such as heat sen-
sitive thermostats, smoke detectors,
and/or electric manual pull stations.
Information on the various types of
separately ordered Solenoid Valves
that may be used with this trim pack-
age is given in Technical Data Sheet
TFP2180. Nominal installation dimen-
sions for the Vertical Electric Actuation
Trim are shown in Figure 4.
NOTE: Approval by Factory Mutu-
al is contingent on the use of an FM
Approved 24VDC Solenoid Valve. FM
only approves solenoid valves for use
in non-hazardous locations.
Consult with the authority having ju-
risdiction regarding installation cri-
teria pertaining to electric actuation
circuitry.
The Electric Actuation Trim is provided
with a Model ASV-1 Automatic Shut-Off
Valve (Item 5 - Fig. 3A and 5); conse-
quently, the release circuit of the Re-
leasing Panel need only provide the
standard ten minutes of alarm condi-
tion intended to energize the Solenoid
Valve to open. After the ten minute du-
ration, at which point should the Sole-
noid Valve become de-energized and
close (especially while operating under
battery back-up), the Automatic Shut-
Off Valve will have already automatical-
ly closed, thereby preventing the DV-5
Diaphragm Chamber from becoming
re-pressurized, and preventing an in-
advertent closing of the DV-5 during a
fire event.
Materials of
Construction
NOTES: The galvanized or brass nip-
ples and fittings for the Valve Trim
provide corrosion resistance and are
intended to extend the life of the instal-
lation of the DV-5 Valve when exposed
to internal and external corrosive con-
ditions. Although these selections are
intended to resist corrosion, it is rec-
ommended that the end user or oth-
er technical expert familiar with con-
ditions at the proposed installation be
consulted with respect to these selec-
tions for a given corrosive condition.
Systems using a seawater or brackish
water supply require special consid-
erations in order to extend the life of
the valve and trim. This type of system
ideally should be configured with a pri-
mary source of clean fresh water (e.g.,
a pressurized water tank) and that only
upon system operation is the second-
ary water supply (seawater or brack-
ish water) allowed to enter the system.
After the system operation, the sys-
tem should be thoroughly flushed with
clean fresh water. Following this rec-
ommendation will increase the service
life of the DV-5 Valve and Valve Trim.
