FDV-PH0
The FDV is a Fire Protection control valve for Deluge fire sprinkler systems, designed for installations in hazardous environments.
The FDV-PH0 is a pressure control Deluge system, actuated hydraulically and resets locally.
When a hydraulic detection system, a Wet Pilot detection Line, is exposed to a predetermined temperature level, its automatic fire sprinklers shatter open, commanding the FDV-PH0 deluge valve to open. Once open, the valve reduces the inlet high pressure to a predetermined fixed outlet pressure. The Deluge system incorporates an emergency valve, bypassing the fire detection system for manual operation.
Designed for vertical or horizontal installation, a globe pattern, line pressure operated FDV-PH0 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.
