Electrically Actuated Deluge Valve 115-4DV
Electrically controlled deluge valve, actuated by the pipeline pressure. The valve is closed in its normal, set position and opens when a 3-way solenoid valve is energized. It closes drip tight when the solenoid valve is de-energized. An emergency manual release valve is fitted as standard.
FEATURES & BENEFITS
Opens quickly when the solenoid valve is activated (specify energize-to-open or energize-to-close)
Manual override to open the valve regardless of solenoid valve position
Visual indicator for indication of valve position
Large supply drain port to drain inlet side piping – globe only
Solenoid operated main valve
No adjustments necessary
Factory tested
Sizes 1.25” (DN32) – 16” (DN400)
Wide range of materials available including those for seawater service
Options available include 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
• ABS type approval
TYPICAL APPLICATIONS

Mining
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], a 3/2-way N.C. solenoid [6] and an auxiliary pilot valve [7].
Under fire conditions, a fire alarm control panel energizes the 3/2-way N.C. solenoid (or de-energizes the coil of a continuously energized ED 100% normally open solenoid for SIL 3-4 rated systems). The pressure in the auxiliary pilot valve increases, causing it to shift position 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.
