DV-5a
Tyco
The TYCO DV-5a Automatic Water Control Valves are diaphragm type valves that can be used in double interlock preaction 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.
