DelugeGuard™ Medium Velocity Spray Nozzle: Advanced Fire Protection for Critical Assets
Protect your high-value assets and personnel from fire hazards with the DelugeGuard™ Medium Velocity Spray Nozzle. Engineered for superior performance in fixed water spray and deluge systems, this nozzle delivers a uniform, high-density cone of water, crucial for effective cooling, exposure protection, and fire extinguishment in demanding industrial and commercial environments.
Overview
The DelugeGuard™ Medium Velocity Spray Nozzle is an open-type (non-automatic) directional spray nozzle designed to discharge a medium velocity spray of water in a specified pattern and K-factor. It is an integral component of deluge systems, activated by an independent fire detection system, which rapidly flood a protected area with water upon activation, preventing fire spread and mitigating damage. Ideal for applications requiring broad, consistent coverage and rapid cooling.
Key Features & Benefits
Optimized Spray Pattern: Engineered to produce a uniform, dense conical spray pattern, ensuring comprehensive coverage and efficient heat absorption.
Effective Cooling & Exposure Protection: Rapidly cools surfaces and equipment exposed to fire, preventing structural failure and protecting adjacent assets from heat damage.
Corrosion-Resistant Construction: Available in high-grade brass or stainless steel (304/316) for exceptional durability and longevity in harsh, corrosive, or outdoor environments.
Wide Range of K-Factors: Available in various K-factors to meet specific design requirements for flow rate and pressure, allowing for customized system performance.
Multiple Spray Angles: Offered in a selection of spray angles (e.g., 65°, 80°, 90°, 100°, 110°, 120°) to provide precise coverage for different geometries and protected objects.
UL Listed & FM Approved: Manufactured to the highest safety and performance standards, ensuring reliability and compliance with international fire protection codes.
Easy Installation: Features standard NPT (National Pipe Taper) or BSPT (British Standard Pipe Taper) threaded connections for straightforward installation into deluge piping systems.
Low Maintenance: Robust design minimizes the need for frequent maintenance, offering a cost-effective long-term fire safety solution.
Typical Applications
The DelugeGuard™ Medium Velocity Spray Nozzle is indispensable in facilities where rapid fire control and protection of critical equipment are paramount. Common applications include:
Oil & Gas Facilities: Refineries, petrochemical plants, offshore platforms, tank farms.

Chemical Processing Plants: Storage tanks, reaction vessels, pump stations.
Flammable Liquid Storage Areas: Loading racks, hazardous material warehouses.
Industrial Conveyor Systems: Protecting critical transfer points and materials.
Aircraft Hangars & Aerospace Facilities: Protecting high-value aircraft and infrastructure.
Internal Strainer: Stainless Steel (optional, recommended for larger K-factors)
Finish
Natural Brass, Polished Stainless Steel
Listings/Approvals
UL Listed, FM Approved (specific models and K-factors)
Standards
Designed to meet requirements of NFPA 13, NFPA 15, and other relevant codes
Materials & Construction
Our DelugeGuard™ nozzles are precision-machined from robust, high-quality materials to ensure optimal performance and longevity:
Brass: A cost-effective and highly reliable material, suitable for general industrial applications where corrosion is not extreme.
Stainless Steel 304: Offers superior corrosion resistance compared to brass, ideal for mildly corrosive environments.
Stainless Steel 316: Provides the highest level of corrosion resistance, making it suitable for aggressive chemical environments, marine applications, and offshore platforms.
The sturdy, one-piece body design, coupled with precision-drilled orifices, guarantees consistent spray patterns and flow characteristics over the nozzle's lifetime. An optional internal strainer (recommended for K-factors above 8.0) prevents clogging from particulate matter in the water supply, enhancing reliability.
Installation & Maintenance
Installation of the DelugeGuard™ Medium Velocity Spray Nozzle should always be carried out by qualified personnel in accordance with local codes, NFPA standards (e.g., NFPA 15 for Water Spray Fixed Systems), and the system designer's specifications.
Ensure correct orientation and spray angle as per system design drawings.
Use appropriate thread sealant for a leak-tight connection.
Regular inspection of the nozzle for blockages, corrosion, or damage is recommended as part of a routine fire suppression system maintenance program.
Deluge systems should be flushed and tested periodically to ensure proper operation
