The Model DDV deluge valve is a diaphragm-type deluge valve available in1-1/2” (40mm), 2” (50mm), 2-1/2” (65mm), 76mm, 3” (80mm), 4” (100mm), 6” (150mm), 165mm, and 8” (200mm) nominal sizes with multiple end configurations.
The valve diaphragm seals against a seat machined in the valve body. Water pressure in the chamber between the diaphragm and the cover presses the diaphragm against the seat to prevent water flow through the valve. The release of water pressure from the chamber allows the diaphragm to deform away from the seat allowing water to flow through the valve.
Maintenance of the valve is simplified because all trim is connected to the valve body, and the diaphragm can be removed without disassembling the trim.
Trim options allow for either remote-resetting (on/off) operation or remote-resetting (on/off) operation with pressure regulation. In both configurations, water flows through the Model DDV valve when the solenoid trim is open. When the solenoid is closed, the Model DDV valve resets and water flow is stopped. The Model DDV is controlled by a solenoid valve in the trim. For UL systems, the solenoid is normally closed and is energized open upon activation of the release control panel. Removal of power from the solenoid causes it to close. For FM systems, the solenoid is a latching impulse solenoid that is energized open upon activation of the release control panel. The latching solenoid requires a separate “pulse” of power from the release control panel in order to close.
