Description
The TYCO DV-5A Automatic Water
Control Valves are diaphragm type
valves that can be used in remote-
resetting deluge fire protection
systems. When properly trimmed,
the DV-5A Valve with Remote-Reset-
ting, Pressure-Reducing Trim can be
opened and closed during a full-flow
condition from a remote location. Key
features are as follows:
• Pressure-Reducing function main-
tains pre-set outlet pressure.
• 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, Pressure-Reducing
Trim is provided by an automatic elec-
tric detection system or remote manual
electric activation. The easily installed
trim configuration for the DV-5A Valve
with Remote-Resetting, Pressure-
Reducing 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 cor-
rosion resistance of the epoxy coating
permits the use of the DV-5A in cor-
rosive atmospheres associated with
many types of industrial processing
plants and outdoor installations.
