The TYCO DV-5a Automatic Water Control Valves are diaphragm type valves that can be used in deluge fire protection systems. When properly trimmed, the double seat design of the DV-5a Valve also provides actuation of fire alarms upon system operation.
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.
The DV-5a features internal and external 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.
The DV-5a Valves are offered with the DV-5a Valve and separately ordered semi-assembled trim shown in Figures 7, 8, and 9, or, for ease of installation, with the DV-5a Valve completely trimmed with or without a System Main Control Valve.
