Operates safely under service pressures of 3 to 14 kg per square centimeter

Fully UL and FM approved when used with compatible foam bladder tank systems

Benefits

Precision is everything in a chemical or hydrocarbon fire. This ratio controller automatically adapts to changing water flow conditions, ensuring the exact percentage of foam concentrate is introduced into the water line without manual adjustment. Its robust bronze or stainless steel construction guarantees long-term durability against harsh industrial environments and corrosive foam agents, drastically reducing maintenance costs and preventing critical equipment failure during an emergency response.

Usage / How to Use

This critical component is installed directly into the main fire water line, typically adjacent to a foam bladder tank or inline balance pressure proportioner. As pressurized water flows through the controller, a pressure drop is created that forces the foam concentrate from the bladder tank into the water stream at the precise required ratio. It is widely used in high-risk zones such as aircraft hangars, petrochemical refineries, and marine fuel loading docks.
