Electrically or Pneumatically Actuated Deluge Valve 116-3FC
Electrically or pneumatically actuated, pilot controlled deluge valve, actuated by the pipeline pressure. The valve is closed in its normal, set position and opens when the pneumatic supply pressure is removed, or by an electric command. An emergency manual release valve is fitted as standard.
FEATURES & BENEFITS
Opens quickly when the pneumatic supply pressure is removed, or when the solenoid valve is energized (specify energize-to-open or energize-to-close)
Manual override to open the valve regardless of pneumatic pilot or solenoid valve position
Visual indicator for indication of valve position
Large supply drain port to drain inlet side piping
Solenoid operated main valve
No adjustments are necessary
Factory tested
UL Listed for deluge service in sizes 3” thru 10”
Can be installed vertically or horizontally
ANSI Flanged Class #150 or Class #300
Wide range of materials available
Options available including opening and/or closing speed controls, limit switch assembly and pressure gauge(s)
CERTIFICATION & COMPLIANCE
• ANSI FCI 70-2 Class VI seat leakage class
• Fire tested to EN ISO 19921
• UL listed under VLFT category
• ABS type approval
TYPICAL APPLICATIONS

OPERATION
The basic control valve [1] used in this deluge system is a diaphragm actuated globe valve which closes with an elastomer-on-metal seal, hydraulically operated control valve engineered specifically for fire protection systems.
In the standby position, the deluge valve is held closed by the upstream water pressure, trapped in the valve’s control chamber. The water pressure enters the control chamber through the priming line ball valve [2], a Y-type strainer [3] and an ejector [8].
Under fire conditions, the deluge valve opens automatically under any of the following circumstances:
1. A fire alarm control panel (F&G panel) energizes the 3/2-way solenoid [6] (or de-energizes the coil of a continuously energized ED 100% solenoid for SIL 3-4 rated systems).
2. The pneumatic pressure is removed.
When this happens, the pressure in the pneumatic pilot [7] drops, causing it to open and allowing the water to drain the deluge valve’s control chamber. The deluge valve opens instantly and allows water to flow the pipeline and through the open sprinklers over the protected area.
Manual emergency actuation is enabled by opening the emergency manual activation valve [5]. The deluge valve opens instantly and allows water to flow the pipeline and through the open sprinklers over the protected area.
A visual indicator [4] provides indication of the valve’s position at a glance.
