Features an auto-reset mechanism for streamlined system restoration
Compatible with ANSI B 16.5 flanged connections for global standards
Versatile mounting supports both horizontal and vertical installations
Complete trim available in NAB or Monel material specifically for sea water use
Flexible actuation options including manual, remote solenoid, or wet and dry pilot lines

Benefits

The H5 Deluge Valve solves the critical problem of equipment degradation in saline or corrosive atmospheres. By using high-grade Nickel Aluminium Bronze, this valve eliminates the frequent maintenance and failure risks associated with standard materials in offshore and coastal locations. Its auto-reset functionality is a major advantage for facility managers, as it allows the system to be put back into standby mode quickly after a test or activation without complex manual disassembly. The high pressure rating ensures that the valve can perform under the intense hydraulic demands of large-scale industrial fire suppression networks, providing a robust first line of defense that protects both infrastructure and lives.

Usage / How to Use

This valve is permanently installed in the main fire water supply line of a deluge system. It is commonly used to protect high-value targets such as oil refineries, chemical storage tanks, offshore drilling platforms, and aircraft hangars. In an emergency, the valve is triggered by the release of pressure in the pilot line or by an electrical signal to the solenoid. Once activated, the valve opens fully, allowing a massive volume of water to flow into the open sprinkler or spray nozzle network to blanket the hazard. After the event, the auto-reset feature allows for a smooth transition back to the standby state once the trim pressure is restored.

Why Choose This Product

Investing in the Model H5 means prioritizing uncompromising safety. The heavy duty Nickel Aluminium Bronze build outlasts standard steel valves in marine environments, providing an unmatched return on investment. Furthermore, the compliance with standard ANSI B16.5 flanged connections ensures easy integration without costly pipeline modifications. With its adaptable trim packages and proven high pressure rating, it stands out as the most reliable, professional grade choice for critical infrastructure protection.
