UL Listed Reverse Action Nozzle MV-C Series

Description

Introduction

The Reverse Action Nozzle is a high-performance fire protection component specifically engineered for use in fixed deluge water spray systems. This specialized nozzle is designed to provide effective cooling and fire suppression for hazards where traditional spray patterns may not be sufficient. With its robust construction and certified performance, it stands as a critical line of defense for industrial infrastructure.

Key Features

Available in multiple corrosion-resistant materials including Stainless Steel, Brass, and Aluminum Bronze.

Integrated strainer options (Stainless Steel or Copper) available in models MV-CS and MV-CBS to prevent orifice clogging.

Wide range of K-factors from 1.3 to 6.75 (US) to accommodate various hydraulic design requirements.

Choice of 120-degree and 140-degree spray angles for precise coverage of specific hazard areas.

Fully UL Listed, ensuring the product meets the highest international safety and quality standards.

Open orifice design allows for immediate and unobstructed water discharge upon system activation.

Benefits

This nozzle offers superior protection by creating a uniform and high-velocity water spray that is essential for cooling surfaces and suppressing fires. The variety of material options allows you to select the perfect nozzle for your specific environment, whether it is a highly corrosive offshore platform or a standard industrial warehouse. By choosing a model with a built-in strainer, you significantly reduce the risk of system failure caused by debris in the water supply, which is vital for maintaining system readiness. The UL Listing provides peace of mind that your fire protection system will perform as intended during a crisis, helping to prevent catastrophic asset loss and ensuring the safety of your personnel.

Usage / How to Use

The Reverse Action Nozzle is typically installed in fixed piping networks within a deluge system. These systems are commonly found protecting large-scale industrial equipment such as electrical transformers, conveyor belts, chemical storage tanks, and cable trays. During installation, the nozzle is threaded into the piping network using standard connections. Because it is an open orifice nozzle, it remains ready for water discharge as soon as the main deluge valve is triggered by a fire detection system. Maintenance involves periodic inspection of the orifice and strainer to ensure they are free from obstruction and that the deflector is not physically damaged.
