Fire protection valve

FDV-DP SERIES

diaphragm

pneumatically-operated

control

* Hydro-dynamic pattern design ensures high flow rates with minimum head loss * The 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 heat. * Soft closing upon pressurization of the valve’s control chamber, by line pressure or other independent water source, prevents surges. 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.
