How It Works – Differential Pressure for Instant Response

The diaphragm-type deluge valve operates on a differential pressure principle. Unlike standard sprinkler systems where individual heads activate, a deluge system keeps all sprinkler heads open at all times.

• Standby Mode: The valve remains closed, as the diaphragm/clapper is held shut by water pressure in the prime chamber.

• Detection: An independent fire detection system—such as heat, smoke, or pilot line sensors—triggers the valve.

• Activation: Releasing the prime chamber pressure allows the clapper to lift.

• Full Flow Discharge: Water or foam is instantly released to all open sprinkler heads, providing complete area coverage and rapid fire suppression.

Key Components

• Valve Body: Robust housing that controls water or foam flow.

• Clapper/Diaphragm: Flexible barrier separating the prime chamber from system supply, maintaining closure under pressure.

• Prime Chamber (Control Chamber): Holds pressure to keep the valve closed until detection occurs.

• Trim Assembly: Includes auxiliary valves, gauges, and piping for testing, draining, and system control.

• External Detection System: Activates via pilot line sensors, electric heat detectors, or smoke/UV/IR detectors.

Applications – Industries Where Speed Matters

Diaphragm-type deluge valves are essential in industries where rapid, total-area fire suppression is critical:

• Aircraft Hangars: Protects aircraft and fuel storage from fast-spreading fires

• Power Generation Facilities: Ensures safety of transformers, generators, and turbines

• Chemical Processing Plants: Secures areas with flammable liquids, solvents, and reactive chemicals

• Oil & Gas Facilities: Refineries, offshore platforms, and storage depots with high fire hazards

• Industrial Processing Units: Conveyor systems, equipment pits, and high-dust environments

• Transformer Protection Areas: Rapid response to electrical and fire hazards in utility sectors
