Overview
The Reliable Model MV Spray Nozzle is designed for use in fixed water spray and deluge systems where dependable directional discharge and uniform coverage are essential. It provides consistent water distribution for fire exposure protection in industrial and special hazard applications, ensuring reliable performance under demanding environmental and service conditions.
Product Overview
The MV Spray Nozzle delivers a stable spray pattern for efficient heat absorption and exposure control. Its engineered orifice and deflector geometry produce uniform droplet formation that enhances fire suppression effectiveness. The compact body design allows flexible installation in both open and confined spaces, such as process areas, tunnels, and equipment enclosures.
Constructed entirely of high-quality brass, the nozzle is available in either a natural brass finish or a corrosion-resistant electroless nickel finish to meet various design and environmental requirements. The precision-machined components ensure accurate flow characteristics and long-term durability, even in challenging service conditions. Common applications include protection of process vessels, conveyors, transformers, steel structures, and other equipment where controlled spray distribution is required to limit fire spread or radiant heat.
Listings and Approvals
The Reliable Model MV Spray Nozzle is FM Approved and cULus Listed for use in water spray and deluge systems in accordance with applicable design standards. Approvals cover a variety of orifice sizes, K-factors, and finishes. All installations must comply with the limitations and conditions of the respective approval listings and governing codes.
Installation and Maintenance
Proper installation is essential to achieve the rated performance of the nozzle. The nozzle must be installed using the manufacturer’s specified wrench and torque settings to avoid thread or seat damage. The deflector must be positioned according to the system design drawings to maintain correct spray orientation and coverage. Care must be taken to prevent debris, paint, or foreign material from entering or obstructing the nozzle orifice.
Once installed, the MV Spray Nozzle should be included in routine inspection and maintenance programs in accordance with NFPA and local authority requirements. Inspections should confirm that spray openings remain clear, orientation is correct, and that no corrosion, mechanical damage, or obstruction has occurred. Any nozzle exhibiting signs of wear, blockage, or impact damage must be replaced immediately. Periodic system flow tests should be conducted to verify overall performance and readiness.
