Pneumatic Actuated with Local Reset Deluge Valve
Deluge Systems
ADVANTAGES
CHARACTERISTICS
The FDV is a Fire Protection control valve for Deluge fire sprinkler systems, designed for installations in hazardous environments. The FDV-DP0 Deluge system is actuated pneumatically and resets locally. When the pneumatic dry pilot detection line is exposed to flame heat, its automatic fire sprinklers shatter-open, while venting the air pressure from the FDV-DP0’s actuator, commanding the deluge valve to open.The Deluge system incorporates an emergency valve, bypassing the fire detection systems for manual operation.Designed for vertical or horizontal installation, a globe pattern, line pressure operated FDV-DP0 valve features a direct elastomeric diaphragm seal. It has no balancing spring or internal metallic wet components in the valve body. The hydrodynamic pattern design, ensures high flow rates with minimum head loss.
Only three parts: body, diaphragm & cover plate. No wet metal spring inside the control chamber Full bore unobstructedSimple manual reset of the valve to standby position without draining or opening the valve itself, neither closing OS&Y or other valves in the systemOpen fail safe valve, maintained in stand-by closed positionLow maintenance cost: the valve is serviced in-line with only one replaceable part which is long life elastomeric diaphragm Conforms with inspection, testing and maintenance standard of water-based fire protection systems, NFPA 25
Hydro-dynamic pattern design ensures high flowrates with minimum head lossThe valve trips open automatically upon a gradual release of water pressure from its control chamber. The trip is actuated by Dry Pilot Line’s pneumatic pressure release due to its exposure to flame heatSoft closing upon pressurization of the valve’s control chamber, by line pressure or other independent water source, prevents surges

OPERATION
SET positionPressurized water in the valve’s control chamber (DL) is trapped by the closed PSA (PA), the closed PA-PTC actuator (PC) and by the closed emergency valve (EU), maintaining the FDV Deluge valve (DL) closed.
FIRE situationWhen some of the Dry Pilot detection line’s automatic fire sprinklers are subjected to flames heat and shatter-open, the pilot detection line depressurizes the PA-PTC control chamber. The PA-PTC (PC) opens and drains the deluge valve’s control chamber.The FDV deluge valve opens and admits water to the spray sprinklers line.
RESET positionSystem reset requires the replacement of all the Dry Pilot detection Line’s shattered-open automatic fire sprinklers.The detection line is then pressurizing together with the PA-PTC actuator, to reset it to closed position.The PSA (PS) push button should be pressed to enable the control chamber filling, closing the FDV deluge valve.
