DV-5A Automatic Water Control Valve
Remote-Resetting Deluge Fire Protection Systems
1-1/2 Inch to 8 Inch (DN40 to DN200)
General
Description
The TYCO DV-5A Automatic Water
Control Valves are diaphragm type
valves that can be used in remoteresetting deluge fire protection
systems. When properly trimmed, the
DV-5A Valve with Remote-Resetting
Trim can be opened and closed during
a full-flow condition from a remote
location. Key features are as follows:
• Remote-resetting feature provides
the ability to reset the valve from one
or more locations.
• Compact, space-saving design
reduces valve room footprint and
construction costs.
• Electric actuation is compatible with
many types of automatic and manual
release options.
• Actuation of fire alarms upon system
operation is provided.
The DV-5a Valves are offered with the
DV-5a Valve and separately ordered
semi-assembled trim shown in Figure
6, or, for ease of installation, with the
DV-5a Valve completely trimmed with or
without a System Main Control Valve.
The diaphragm style design of the
DV-5A Valve allows external resetting,
providing for easy resetting of a deluge
system without having to open a valve
handhole cover to manually reposition
a clapper and/or latch mechanism.
Simply re-pressurizing the diaphragm
chamber resets the valve.
Operation of the DV-5A Valve with
Remote-Resetting Trim is provided by
an automatic electric detection system
or remote manual electric activation.
The easily installed trim configuration for the DV-5A Valve with RemoteResetting Trim provides for emergency
(manual) release of the valve at the
valve location.

The DV-5A features internal and exter-
nal coating of the valve to provide
corrosion resistance. The external corrosion resistance of the epoxy coating
permits the use of the DV-5A in corrosive atmospheres associated with
many types of industrial processing
plants and outdoor installations.

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 1-1/2 in. to 8 in.
(DN40 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
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:
•
Deluge Remote-Resetting Trim is
232 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 Pressure
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 normally open valve.
External trim connections are NPT
threaded. EMEA trim is provided with
NPT x ISO 7/1 thread adapters.
For 8 in. VdS approved Deluge RemoteResetting Trim, the maximum velocity
for this valve application is 7.5 m/s.

Design
Criteria
The following items must be considered and applied accordingly for T YCO
DV-5A Valve with Remote-Resetting
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 system as it pertains to the possibility of an inadvertent remote closing of the DV-5A Valve
during a fire condition. 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 accordance 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 necessary. For more information, refer to
Technical Data Sheet TFP1632.

REMOTE-RESETTING SCHEMATIC DIAGRAM
Operation
The TYCO DV-5a Valve is a diaphragm
style valve that depends upon water
pressure in the Diaphragm Chamber
(Ref. Figure 2A) to hold the Diaphragm
closed against the water supply
pressure.
When the DV-5A Valve with RemoteResetting Trim is set for service, the
Diaphragm Chamber is pressurized
through the trim connections from the
inlet side of the system’s main control
valve.
With reference to Figure 4, initial activation of the Solenoid Valve due to
noid Valve. Opening of the Solenoid
Valve in the Remote-Resetting Trim
releases water from the Diaphragm
Chamber faster than it can be replenished through the Restriction in the
Diaphragm Chamber Supply Connection provided in the trim. This release
results in a rapid pressure drop in the
Diaphragm Chamber, and the force
differential applied through the Diaphragm that holds it in the set position
is reduced below the valve trip point.
The water supply pressure then forces
the Diaphragm open, permitting water
to flow into the system piping, as well
as through the Alarm Port to actuate
system alarms.

To remotely reset the DV-5a Valve,
the voltage to the Solenoid Valve
must be transferred to the appropriate terminals of the Solenoid Valve
(Ref. Figure 5) resulting in the latched
closure of the Solenoid Valve. Closing
of the Solenoid Valve in the RemoteResetting Trim permits the Diaphragm
Chamber to repressurize. This repressurizing results in a pressure increase
in the Diaphragm Chamber. The resulting force repressurizes the Diaphragm
Chamber, closing the valve and stopping the flow of water into the system
piping.
