1/2 Inch Medium Velocity Water Spray Nozzle UL FM

Description

Introduction

The Medium Velocity Water Spray Nozzle is a precision-engineered fire protection component designed for use in fixed deluge water spray systems. It is specifically built to protect high-risk equipment and hazards by providing a uniform cooling and extinguishing water spray. These nozzles are essential for maintaining the integrity of industrial structures and machinery during a fire emergency.

Key Features

Open orifice design engineered for seamless integration into deluge water spray systems.

External deflector creates a stable and consistent solid cone discharge for maximum coverage.

Wide range of K-factors available to meet specific hydraulic design requirements.

Multiple spray angle options ranging from 65 to 160 degrees for targeted protection.

Durable construction with permanent markings including model, batch, angle, and K-factor.

Fully UL Listed and FM Approved ensuring international safety and performance compliance.

Lloyd’s Register Type approval specifically for demanding marine and offshore applications.

Compatible with FM approved blow-off plugs to prevent orifice clogging from debris.

Benefits

This nozzle effectively controls and suppresses fires by delivering water at a velocity sufficient to penetrate the flame zone while cooling surrounding surfaces. Its open design ensures that when the system is activated, there is no delay in water delivery. The wide selection of K-factors and angles allows engineers to customize the water density for specific hazards like transformers, storage tanks, or chemical processing equipment. This customization leads to more efficient water usage and better overall protection for your valuable assets. By using a certified nozzle, you ensure that your fire protection system meets local and international insurance requirements.

Usage / How to Use

These nozzles are typically installed in a fixed pipe network around a specific hazard, such as a large oil-filled transformer or a flammable liquid storage tank. They are used in deluge systems where the piping remains dry until water is admitted through a main control valve upon fire detection. To install, ensure the 1/2 inch threads match your piping system and apply appropriate pipe sealant. The external deflector should be oriented to cover the intended area based on the pre-determined spray angle. Regular inspection is required to ensure the orifice remains clear of obstructions and that the deflector is not damaged or misaligned.
