INSTALLATION GUIDE FOR DELUGE VALVES

Deluge valves are critical components in fire protection systems, especially in high-risk areas or large-scale sprinkler networks. These valves allow rapid water discharge throughout the system upon receiving a fire signal, effectively protecting property and personnel.

1. Introduction to Deluge Valves

• Operating principle: A deluge valve is normally closed and only opens when triggered by a fire alarm system or control device. When activated, water or fire suppression agent flows immediately into the piping network and all connected sprinkler heads.
• Applications: Warehouses, chemical plants, oil & gas facilities, flammable material storage areas, airports, ports, etc.
• Advantages: Provides simultaneous water discharge, fast response, reduces fire spread, and easily integrates with existing fire alarm systems.

2. Preparation Before Installation

Before installing a deluge valve, check and prepare the following:

1. Piping and accessories: Ensure the pipe size, material, and condition match the valve specifications.
2. Installation location: Choose a visible, accessible location for maintenance and inspection. Avoid hidden or hard-to-reach areas.
3. Supporting equipment: Prepare shut-off valves, pressure gauges, control chambers, test valves, etc.

3. Installation Steps

Step 1: Install the main valve into the system’s main pipeline.

• Ensure flow direction matches the arrow on the valve body.
• Use genuine gaskets, bolts, and nuts to ensure a tight seal.

Step 2: Connect the control and fire alarm system.

• Integrate the valve with the fire alarm control panel or pneumatic/hydraulic actuators.
• Verify that all solenoid valves or control devices function correctly.

Step 3: Check pressure and perform valve testing.

• Open the main shut-off valve and monitor system pressure.
• Conduct a water flow test to ensure all sprinklers are activated rapidly.

Step 4: Complete installation and schedule routine maintenance.

• Label and protect the valve and associated components.
• Follow manufacturer guidelines for regular inspection and maintenance to ensure reliable operation.

4. Installation Notes

• Always comply with national fire protection standards (NFPA or Vietnam regulations).
• Verify size, pressure, and media type before installation.
• Do not modify the valve or piping structure, as it may cause leaks or prevent proper operation.
• Train personnel to perform regular inspections and system tests.
