Mobile foam unit is an important part of firefighting equipment from mobile foam unit factory. And help to fight fires effectively. An important aspect of these installations is the fire damper, which plays a vital role in controlling the flow of foam solution and water to the nozzles. Fire dampers are designed to help firefighters control the flow rate of water and foam and prevent over-pressurization of the system. In blog post, we’ll take a closer look at how fire valves work on mobile foam installations.

What Is Fire Valve And How It Works?
Fire valves are typically located between the foam concentrate tank and the discharge nozzle on a mobile foam unit. The valve is designed to regulate the flow of foam concentrate and water to the nozzle, allowing the firefighter to adjust the flow rate to suit the needs of the fire.
The valve consists of several components, including a valve body, a valve stem, and a handle. The valve body is typically made from brass or stainless steel, and it contains the internal components of the valve. The valve stem is a cylindrical rod that extends through the valve body, and it is connected to the handle. When the handle is turned, the valve stem moves up or down, opening or closing the valve.
The valve also contains a diaphragm, which is a flexible rubber or synthetic material that helps to regulate the flow of water and foam concentrate. When the valve is opened, water and foam concentrate are allowed to flow through the valve body and into the discharge nozzle. As the flow rate increases, the diaphragm is pressed against the valve seat, which helps to regulate the flow and prevent over-pressurization of the system.
Fire Valves Are The Pressure Relief Valve
Another important component of the fire valve is the pressure relief valve. This designation may prevent over-pressurization of the system. If the pressure in the system exceeds a certain level, the pressure relief valve will open. So that it allows excess pressure to escape. This helps to prevent damage to the foam unit and ensures that the system operates safely.
What Difference Between Foam Hydrant & Mobile Foam Unit
When it comes to firefighting equipment, there are two primary types of foam delivery systems – foam hydrant & mobile foam units. While both systems are designed to deliver foam to extinguish fires, there are some key differences between them.
A foam fire hydrant is a fixture that is usually connected to the municipal water supply. The system consists of many components. It includes foam concentrate tank, foam proportioning system, and a network of pipes and valves. These components drive system to deliver the foam to the fire hydrants. When activated, foam hydrants deliver a fixed volume of foam concentrate to the water supply and then to the nozzles.
One of the key advantages of a foam hydrant is that it is a fixed installation that can deliver a large amount of foam solution to a fire quickly. This makes it well-suited for protecting large industrial facilities, airports, and other high-risk areas. However, foam hydrants are typically expensive to install and maintain, and they are not portable.
In contrast, a mobile foam unit is a flexible and portable system that can be deployed quickly to the site of a fire. This makes it well-suited for firefighting operations in remote or hard-to-reach areas. Mobile foam unit is also more cost-effective than foam hydrant. As they do not require a fixed installation and can be transported to different locations as needed.
