Electrically Actuated Deluge Valve 115-1DV
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
Simple design utilizes a 3-way solenoid valve that directly operates the main valve
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
Standard sizes 1.25” through 4”
ANSI Flanged Class #150 or Class #300
Wide range of materials available
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
Automatic or Manual Actuated Fire Suppression Systems
Petrochemical, Oil & Gas Installations

The basic control valve  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 [4A], a Y-type strainer  and a 3/2-way solenoid .
Under fire conditions, a fire alarm control panel energizes the 3/2-way N.O. solenoid (or de-energizes the coil of a continuously energized ED 100% normally closed solenoid for SIL 3-4 rated systems). Water is drained the deluge valve’s control chamber through the 3/2-way N.O. solenoid. 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 [4B]. The deluge valve opens instantly and allows water to flow the pipeline and through the open sprinklers over the protected area.
A visual indicator  provides indication of the valve’s position at a glance.
