Medium Velocity Water Spray Nozzle MV-E

At Avinash Protection Systems, our Medium Velocity Water Spray Nozzle MV-E is a high-performance fire protection component engineered for use in fixed deluge water spray systems. It is aimed at providing good and controlled water supply in fighting fire to cool surfaces and exposing industrial and high hazard places. This nozzle is also constructed to be very durable, has flexible configuration, and other internationally approved, which makes it suited to the arduous fire safety application where reliability and uniformity is very essential.

Construction and Material

Model MV-E is made of aluminium bronze which is a material that has great resistance to corrosion, strength, and durability. This renders the nozzle to be especially well adapted to the tough working conditions, such as marine atmosphere, offshore workplaces, and in factories where exposure to moisture, chemical or extreme temperatures is typical. Its strong construction gives it a long service life with low degradation hence preserving the integrity of the systems in the long run.

The nozzle body is precision machined and its body dimensions are correct and ensure uniform performance. This focus on quality of manufacturing enables the nozzle to have consistent spray properties during the lifecycle of its operation despite sustained exposure to demanding environmental stress factors.

Design and Operating Principle

The nozzle has a non-automatic design with an open orifice that is meant to be used on deluge valve systems. With this type of systems, all the nozzles release water at the same time in case of the deluge valve being opened. It provides the ability to discharge water over the area that is being guarded instantly and consistently, which is very crucial to controlling fire and absorb heat.

Predictable water distribution is achieved by a fixed spray pattern that is easy to design the system and perform hydraulic calculations. The combination of the external deflector creates solid cone discharge which makes it possible to penetrate and cover water. The spray pattern is especially useful in cooling uncovered surfaces, putting out fires and radiating heat in dangerous areas.

Spray Characteristics and Performance

The nozzle has an extensive selection of spray angles, the designers can choose the most appropriate one in regard to certain hazards. Small spray angles give it high concentration of water, whereas large angles give it a wide coverage. This is practical in allowing efficient spacing of nozzles as well as optimum system layout minimizing wastage of water and still managing to protect it effectively.

There are a variety of sizes and K-factor choices of multiple orifice sizes in both US and metric measures. This broad range allows specific hydraulic design and flexibility to various pressures and flow demands of water supply. The nozzle provides a variety of combinations, which allows tailored solutions to meet the individual requirements of the various installations.

Connection and Finish Options

The nozzle is fitted with standard 1/2″ BSPT or NPT threaded connections making it compatible with the widely used piping systems the world over. This also ensures that it can also be used in both new installations and retrofit projects as it reduces the complexity of the installation, not to mention the downtime.

It can be finished in many different modes such as natural finishing and plated finish like the bright nickel chrome. These finishes are not only corrosion resistant, but also allow visual identification and visual conformity with the system requirements.

Identification and Traceability

Additionally, any nozzle body will be permanently labeled with the key information such as the model number, the batch number, spray angle, and K-factor. Approval agency marks of certification are also displayed in a clear manner. These marks enable easy identification in the process of installation, inspection, and maintenance, and also provide complete traceability to assure quality, as well as in compliance.

Permanent and clear markings assist operators and the inspectors in ensuring that the appropriate type of nozzles are installed and maintained as per the design of the system and other regulations.

Approvals and Certifications

The product is certified and tested to have high international fire protection measures. It is UL Listed, FM Approved, and Lloyds Register Type Approved and this is an assurance that it is an apt component to be used in regulated and installations that are safety critical worldwide. These certifications assure the engineers, consultants, and end users on the performance and reliability of the nozzle.

The blow-off plug is an FM Approved design. The feature provides the orifice with protection against debris, dust or similar substances during installation and maintenance and provides free flow of water when the system is switched on.

Applications

The nozzle is commonly applied in industrial fire protection systems where high discharge rates and low spray patterns are needed. Common uses are oil and gas plants, petrochemical plants, power plants, transformer protection, conveyor systems, loading racks, and storage areas that have flammable or combustible substances. It can also be used in exposure protection whereby equipment or structures around it need to be cooled in order to stop fire.

Reliability and Maintenance

The plain and rugged design reduces the maintenance demands and provides the stability of the continuous performance over time. The nozzle is extremely wear and service resistant as it has no moving parts and has a strong body material. The system can be kept in working condition and be used in accordance with the safety requirements due to regular check-ups and simple maintenance.

This product provides reliable performance in fire protection in a broad selection of industrial uses by incorporating durable materials, design flexibility, and global certification. The Medium Velocity Water Spray Nozzle is engineered to support effective fire risk management, protect valuable assets, and enhance overall safety. It is a reliable option that is trusted to solve critical fire protection systems in the world due to its proven design, flexibility, and reliability.
