Pressure Reducing Deluge Valve, Pneumatically Actuated, Remote Reset
The FDV is a Fire Protection control valve for Deluge fire sprinkler systems, designed for installations in hazardous environments.
The FDV-PP1 is a pressure control Deluge system, actuated pneumatically and resets remotely.
When the pneumatic dry pilot fire detection line is exposed to flame heat, its automatic fire sprinklers shatter- open, venting the air pressure from the FDV-PP1’s actuators, commanding the 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 systems for manual operation.
Designed for vertical or horizontal installation, a globe pattern, line pressure operated FDV-PP1 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.
