Diaphragm valve

FDV-DC SERIES

electropneumatic

control

for water

* Hydro-dynamic pattern design ensures high flowrates with minimum head loss. * The valve trips open automatically upon a gradual release of water pressure from its control chamber. The valve is actuated by an electric signal conveyed to the valve’s solenoid or 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-DC1 resets to stand-by close position by de-energizing the alarm system solenoid’s coil through the main control panel or, pressurizing the Dry Pilot Line The FDV is a Fire Protection control valve for Deluge fire sprinkler systems, designed for installations in hazardous environments. The FDV-DC1 Deluge system is actuated electrically or pneumatically and can be reset from a remote location. Two detection systems, can independently activate an actuator to open the deluge valve: a pneumatic Dry Pilot detection Line and/or an electric solenoid, connected to sensors through a control panel . 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-DC1 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.
